I might convert from sonnb's XenGallery to XFMG. Does it convert *everything* (tags, comments, etc.)? I also use Nobita's Groups mod, which integrates with XenGallery. Does XFMG support this? Also, what kind of widgets can I setup? I currently have 3 sets of widgets that display various updated picture albums, etc.
Lastly, is it reversible? Like if I *try* it, can I then simply "disable" the add-on and go back to how it was, or will the conversion move/rename files?
