The problem with the claws interface is that the little folder triangles, for collapsing parts of the tree, are too small. It's VERY easy to miss them. And I couldn't zoom in and out of that list view, IIRC. I also find that some actions just aren't very intuitive. I feel like they made some UI choices that probably work very well for their desktop version, but end up feeling shoe-horned in the PDA version.

I didn't always like Mozilla's IMAP implementation, but Thunderbird (TB) 1.x was "good enough", and TB 2.x has a HUGE feature win: the way you can select whether the folder list is "all folders", "folders with unread messages", "folders marked as favorites", or "folders you recently accessed". That is a HUGE usability win, IMO. And I don't know of any other mail client that does those.

I asked claws to implement it, though. And they said no. Which is a shame. It would have really helped with using the tiny screen if I could limit the folders shown, without limiting the subscription list. And limit it based on dynamic considerations (like "has unread messages" or "recently seen" or "marked as favorite").

Maybe after they finish microb, someone will work on porting a TB based mail client to maemo. I would _LOVE_ that. Especially if it has the folder view selection I mention above.
