"I'd like to be able to search through my History window. Ctrl+F should bring up the find box, which should filter what shows up in the History window to show only things that match the find text."
Okay, I first misread this as wanting to add my Find's to the History panel. Rereading I realized it is requesting the ability to use a Find statement within the History panel - a much more important request. At least I got to laugh at myself.
This could be a very useful addition.
