there are lots of little things that could be considered bugs that need fixing; we can discuss them here.
one is the new focus capturing, which keeps F&R always the focused window. this is good to prevent losing focus by accident, but as kfitting pointed out, it is not good if you purposefully want to switch windows while f&r is on screen. this needs to be fixed.
another issues pointed out by someone (i forget who) is that when you select a group alias, it should show all items, and ignore normal limits.
config options need to be better organized, split into dif pages.
shortcut links sometimes not launching in proper 'working directory'.
more?
