• Fixed the bug knew as: "Missing the auto-clear functionality that the Quickfilter box exhibits when you switch to a different folder -with persists button off-".
  Now this works fine, when you use Unified Search Widget to filter and open another folder, text and options in the widget will be resetted, just like standard Quickfilter does; if the persists button is on, of course, nothing is reset and filter is applied to the new opened folder.

Fixed a Thunderbird bug (filled at bugzilla like "Bug 582576") similar to previous issue: when you use the filter (standard Quick Filter) and then open a folder that is the 'root folder' or 'account folder', filter options are not cleared but filter is not applied looking de-synchronized. Unified Search 0.6.3 solves this and ensure this not happen in the Unified Search Widget.

• Some minor issues that de-synchronized options between Quick Filter, Unified Search Widget and Global Search in some concrete cases.

The major feature at this release is the new 'Unified Search Widget' that include 'almost all' the features of the 'Quick Filter Bar' in a more lightweight widget that use less vertical space and let you place it wherever you want. The widget let you do global search too, unifying the best of Thunderbird quick filtering and global search with autocomplete.
It's based on the idea posted at Bugzilla Bug 570815 "qfwidget", their mockups, and mixed with the 'Unified Search' idea posted at Bug 526221 and implemented at this extension.

Another changes at this release are:
- A new option called: "Remember filter options". By default, Thunderbird remember the filter options that you use in your last session; now, you can disable this behavior setting 'off' this new option, that apply both standard filter bar and the new widget.
- All the 'filter text-boxes' are synchronized when some filter is applied, to avoid confusions about what filter is being applied.
- Stronger initialize system, that avoid some type of strange errors of previous versions, and another minors bugfixes.
