damn 16 months? lxde updates more frequently than that and its a much smaller project. but, i think i'd still be interested in trying xfce after not trying it for maybe 3 years.
Crap, I follow both git repos, and LXDE doesn't get a meaningful commit (with meaningful I mean anything but translations) in months, while several subprojects of XFCE get them in a daily basis.
How many new features did LXDE commited last year? The only one I can think of is getting back the tree view in PCManFM.
Also, LXDE didn't achieve even their first stable release.
I love both projects for different reasons, though.
I admit Thunar is pretty basic, I don't use it because of the lack of tabs, for example, and use PCManFM instead.
I really hope they fixed thunar. It displays "eject buttons" for all volumes and it also shows them on the desktop even if they are not mounted. It's really annoying. There's a bug submitted for this since 2010. Ugh.
