Double-tap speed

Would it be possible to add a setting for the double-tap activation speed? The delay seems to be set too high. There are times where I’ve hit CMD (my double-tap key) twice consecutively not intending to trigger the double-tap action, but TotalTerminal still activates.

Doing a rough test right now, it seems I can wait as long as 1 second between taps and still trigger the terminal. Typical double-clicks have a much shorter delay, but for customizability, I’m sure others might have different preferences.
