So far I like the latest version of Thunderbird - enough to have spent time re-creating my filters on 5 different accounts from Postbox since POSTBOX DOESN'T LET YOU EXPORT FILTER RULES. Argh.
The Send Later add-on doesn't seem to work with the new version, though, which is a bummer. Am hoping it or something like it will at some point.

Oh, and I sure miss being able to search for "Thunderbird" and "Send Later" here without needing hashtags . . .
