Rated 5 out of 5 stars

This is my one and only theme; I love it. I have only one small request.

Can you make the Lightening Calendar icons smaller when:
Right clicking --> Customise --> Use Small Icons.

Hopefully the size of the icons for "Mail, Calendar, Task" will be the same height as the "Get mail, Write, Reply, etc" buttons.

Just a thought; great theme.

This review is for a previous version of the add-on (1.8.56). 

In TB2, just right click on the calendar buttons and select 'smaller'.
In TB3, the calendar icons are replaced with calendar tabs with smaller icons only.
