yay! 455 lines maybe you like #1445 button and button-UI ideas too? #1491 i didn't read much or test yet, but ask by default / just to be complete: How much code runs always? (most ImprovedTube code runs only when enabled by the user. When running by default it can wait for an event (such as hold duration) before all else.) And generally, if there is any probability somebody will accidentally use a feature then, we could have a toggle to disable or lock it or the trigger event could be dynamic, also depending on when was the last time the user has changed any of our settings (seconds ago or month) - or anything)
