The only remaining annoyance for me, and one which I don't think is "fixable"... say your left pane is a terminal and you've got a few pages of output (cat something). The right pane has a file open on vim, where you're making notes. As you scroll through the long output you want to select a chunk of text and then paste it into vim, and then carry on scrolling as you hunt for the next clue. Except that the instant you select text, focus returns to the prompt at the bottom of the pane. You compete lose your scroll position. It's intensely annoying. The workaround is "don't do it that way", which is fine until you forget and end up shouting at your computer.
