Option to change activation key duration

[MailYouLater]

Hello, I'm having an issue where sometimes MATVT gets activated by a single, short press of the key it's set to detect. (Toggle option is disabled, so it should only activate when long-pressing this key.)

I'm guessing the device's input handling is a bit sloppy (I've noticed that other apps sometimes register a long-press instead of two short-presses in quick succession) so I'd like to have an option in the settings to customize how long (in miliseconds) a long-press has to be for MATVT to activate on this device, so it doesn't keep getting accidentally triggered by single (or double) short-presses.

Oh I see
Sure

I'll try to get this in with next stable release.
