Version 2.1.682 137.0 KiB Works with Thunderbird 3.0 - 3.0.*

Version 2.1.675 137.0 KiB Works with Thunderbird 3.0 - 3.0.*

Partial re-write for Thunderbird 3.0.
This version is only working with Thunderbird 3, all other application support (Thunderbird 1.x-2.x, Seamonkey) has been dropped.
ThreadVis is now using the new global message database available in Thunderbird 3, so no separate index or cache is built and needs to be maintained. This means no more waiting for messages to be indexed and a more coherent picture of threads.
Added email body preview to tooltips.
Time Scaling now supports logarithmic scaling in addition to linear scaling. Additionally, minimal time difference can also be set manually in preferences.
Timeline font size now configurable in preferences.
Show error conditions in status bar icon (missing messages, out-of-date index, corrupt message database).
Extended context menu in status bar.
Currently, it is not possible to navigate between messages when a message is opened in a new tab (seems to be a limitation of Thunderbird).
Code restructured, avoid global namespace pollution.
Support for cut/copy/paste is currently removed, but will be re-added with a later version.

Version 1.1.595 185.0 KiB Works with SeaMonkey 1.0 - 1.1.*, Thunderbird 1.0 - 3.0b1

New caching backend using a SQLite database. Expect a massive speedup in thread calculation, especially for very large mailboxes.
Ability to abort/restart initial, long-running thread calculation. Closing Thunderbird while a calculation is running preserves already calculated messages and automatically continues the next time Thunderbird is started.
Released under the GNU AGPLv3.
