I'm looking to replace TotalTerminal with iTerm (since TT doesn't work on El Capitan without making OS X less secure), and tried using a function key to hide/show a small iTerm window, but while that does work, the problem is that when it shows the small window, it also shows my regular large iTerm window as well (which I have always running) and the times when I want to show the small iTerm window I don't want the large iTerm window obscuring what's behind it.
Not sure if I explained that well, but that's what I'm hoping to find a way how to do: basically have a small, TotalTerminal-like iTerm2 window that pops up when I hit a certain keyboard shortcut, without also bringing up any other iTerm2 windows that I may have running in the background.
I'm also open to suggestions for other TotalTerminal replacements that work on El Capitan.
