Consistent feature use is still lacking:
Modify Tag Assignments REALLY needs the 'hammer/wrench' options button so that tag categories can be collapsed.
Collapsible windows and panes REALLY need to be able to remember their last use, ie., if I collapse everything in the navigation pane (left column) while working in Mechanics Reference except for the Spells Category, it would be really nice and very helpful if it stayed that way so that I don't have to scroll all the way down again. Yes, I could merely collapse everything each time but you did ask for feedback...
The reason I mention it is because the Assign tags window does remember it (yet has no collapse all for when I am first choosing the tag categories I need, because when you are just entering feats for instance, you really only need the Publisher/Rule/Source categories open).
None of these are urgent, just things that should be considered going forward, as I am certain you have several thousand on the possible TO DO list.
