This is all done using Entire Library from the Quick Search bar
1) Search node isn't expanded to show the current search when searching
2) Quick Search doesn't remember past searches, so past search drop-down shows empty when typing
3) I was able to right click on a search node that wasn't selected without selecting it. Many of the options in the context menu like Remove were disabled.
a) Select some non-search node
b) Click in Quick Search textbox
c) Right click on a search result node
4) When removing searches from Search node leaving it empty it still shows, I think it might be nice it auto-hides when it has no searches and isn't selected.
Tested on skinned 1345 on XP. Can anyone confirm any of these issues?
