I think this should also be discussed on usuability mailing list..

Very good ideas for those two..

I have to agree with that.. With more specialized/powerful news
aggregator, I'm not sure Evolution aggregator is still useful..

Agreed..

Well, my only problem is for people (like me) who have a LOT of folders
(I have 50 folders, some embedded in others) instead of vfolders (they
are too much memory intensive when monitoring a lot of mailing lists,
like me..). These 6 buttons are very space consuming and I don't know
how it will look like without etree.. Maybe a drop-down list (a la
Nautilus, but with icons) would be better instead of the 6 buttons..
