Hi Benny,
MailMate gets better with every version (from great to greater),
there are however so many hidden preferences (via command line
"defaults") that one can set, that it's hard to explore them by
reading the mailing list archives, Changelog, etc.
To explore those gems (some I've used myself, also based on your
reactions to e.g. my tickets) I wonder whether it would make sense
to allow everyone to use them (at their own risk), e.g. by adding
an "Advanced" tab to the preferences and then have a table with the
setting name, maybe a short description, and the value. Also
chrome://flags for Chrome is a good
example how to give users all options.
I would understand if you think that's dangerous and has the
risk to create more support workload, on the other hand it would be
really great for all users. It would also make it a bit easier for
new features to come with new versions, but have them disabled by
default.
