It's a good program. But I like to have a print-command for the "Aufgabe" like for the "Termine" or for both together.

Serious problems with events disappearing and the necessity to restart app when reloading calendars (yes, I understand the checkboxes next to the calendar names)....... Also noticed that write failures are not handled very well along with read failures that are not reported. Setting a new remote calendar with a typo reveals that there is no warning that an ics file could not be found for the average user and therefore can lead to misunderstanding that all is well when it is in fact not.

Product is decent enough, as far as it goes, but without PDA/smartphone sync for Palm and Windows Mobile devices, to say nothing of BlackBerries and iPhones, Lightning/Sunbird is a non-starter for many people (me, for instance). I would bet that Thunderbird usage would skyrocket if only Lightning with PDA/smartphone syncing became available.

This serious shortcoming has been a source of complaints since at least late 2006 - an ETERNITY in the software world. WHY are you dragging your feet so badly on adding this essential feature?

Also, Lightning/Sunbird needs better import/export tools - MUCH better in fact. Won't import or export to enough formats. HTML email is often messed up in the importing process and it is often easier to transfer addresses BY HAND than to fix the terribly mangled results of an address book import!

Good God, people! This project has been going more than long enough for it to have reached a decent level of polish by now!

Lightning is a really nice add-on, but it still lacks some functionality:
1 - Option to hide the side panel, that would reduce a lot the screen clutter
2 - Multi week view, there is an extension to do that, but it doesn't work on tb 2.0.0.*
3 - Better alarm system, with more options
4 - Invite system, similar to the one found in Google calendar. (BTW there is a great extension to use Google calendar in Lighting)
The development has been really good so far, so thanks to those that have worked on this and congratulations!
KAH, Thanks for the 86-64 link! That and i686 links should be on the lighting page, no hidden in a repository ;)

I really want to have this Lightning like calender extension in Thunderbird, however this Lightning compulsorily consumes a lot of my precious screen real estate. I wish if there was an option to hide that dominant calender (and still have its functionality).

Though this site does not provide a link to it, there is actually a 64-bit version. You can find it here: http://releases.mozilla.org/pub/mozilla.org/calendar/lightning/releases/0.5/contrib/linux-x86-64/

See the plugin homepage for other platforms.

This is one of the few missing items I need to completely switch form Windows to Linux. I have been suing the windows version for a while. Works great on Windows.

Anyway to make the Calendars, Agenda, and To Do tabs disappear? All I really want is my files, and be able to take a quick glance at the month and click on a day if I need it. I think the tabs are a bit too much information when I'm trying to take care of e-mail. Other then that, Excellent job you guys! I've already stored dozens of tasks. I know it's a work in progress but so far so good.

Why isn't this version of Lightning compatible with Thunderbird. I download it and it says not compatible!!!!

It's nice to see 0.5 finally out - good job! It looks like that was no small feat, however like a few others I'm disappointed that usability hasn't really moved forward a whole lot from the previous release. For example, adding new events or dealing with reminders is still somewhat crude. The inability to search calendar items or display them as a list is also a major drawback. I just hope that all the behind the scenes work that went into this release will facilitate substantial usability improvements in future releases.

I elected to install Sunbird since it appears there is no way to hide the calendar on the left pane unless needed (maybe it does, but I want and app that just works without searching for functionality). It sits there taking up a lot of room that I would rather use with my address book extension. It is like having to have the calendar open all the time. I might as well then use Sunbird. When it matures more and allows itself to be hidden and shown as needed, I'll try it out again. After all it is still pre-1.0.

I'm so glad that I'm able to have a calendar function in thunderbird. Just don't count on having your event alarm pop up when it's suppose to. I don't know if other people have had this problem, but I get it all the time. It may be because I have an event set to repeat and it's not a one time thing.

Let me give an example of one of my events. I have and event set for 2pm every Monday and Thursday. It went alerted me correctly the first time, but after that I always get my alert pop-up long after I need it. I usually have to close down Thunderbird and reopen it in order to get my event alert. This defeats the purpose of needing an event alert, because now I have to remember to restart Thunderbird at 2pm. LOL! Sometimes I'll even get my event alert a couple days after I'm suppose to. This is quite annoying.

Hopefully this little bug is fixed. I have tried removing the repeating event and adding it again, and it did not solve the problem. Currently this calendar is only good if you glance at it for all day events and holidays.

I like the Calendar for Thnderbird. In some parts of the world week numbers are used a lot, I miss these in the calendar just installed.

Not having a calendar function was one of the drawbacks of Thunderbird for me. This extension helps solve that and it goes a long way to correcting this problem. Overall, I like this a lot, especially with the Provider for Google Calendar extension. Problems: tasks don't appear on the calendar, does not import from Outlook directly (got around this by using Plaxo, then synching with Google), and cannot drag an email to a date to create an event.

Good job on this! It has been extremely useful to me. I have one big beef with it, though. There is no "Add Task" button! I use tasks and events about evenly, so I need a button so that I can easily add tasks quickly! With this, this product would be perfect. Thank you!

Handy, lightweight calendar. No need to recreate Outlook. Thanks.

Lightning is a great extension. Although there are a few kinks in the add on itself (as explained by other reviews), but I'm sure the next version will take care of that...I hope.

It's not complicated, but yet, it isn't too simplistic.

Overall, I get it two thumbs up.

Looking good so far, but needs to get some of the basic issues nailed down pretty quick. i.e. TB restart required to get correct date. Duplication of items in agenda on calendar reload. Lack of choice for display in toolbar.

I do not need an elaborate calendar/scheduling system. And this gives me exactly what I wanted all in one place with all the right features.
