Btw are you planning any thunderbird and contacts support at all?
Actually no. With Gmail and all that web stuff I can easily search in my e-mails and contacts from any computer with internet connection, not just from the computer where my e-mail client is installed. That's why I abandoned thunderbird a long time ago, and why I never really felt the need to go beyond document indexing.
Furthermore, I think it would somewhat bloat up the user interface and the search results, making the program less usable for what it was originally written, that is, document retrieval. For a more detailed explanation, you can read the "Comparison To Other Desktop Search Applications" section on the DocFetcher website
You can, of course, try to convince me otherwise
Btw, the other reason why I left thunderbird behind is that I've lost hundreds of e-mails because I forgot to include them in the backup before formatting the disk. FUCK... Lesson learned: Don't use programs that store important data in obscure "profile" folders.
