Nice idea. Doesn´t work, though. Rated 1 out of 5 stars

I was using version 1.0.2 on Thunderbird on a WinXP machine.

First let me state that this tool is potentially very useful. I hope that this tool will work some day.

The feature I found most irritating was that despite my checking the appropriate box under the settings I was never ever asked when a conflict arose between server and local data. Example: when I had 4 to-dos on the server, but 6 stored locally, the program simply deleted the two unmatched local items (it did this dozens of times). This really is a kiss of death for any synchronization tool, sorry.

This review is for a previous version of the add-on (1.0.2).
