Tie support with repeats
Currently it is impossible to notate and have correct playback of ties across repeat barlines, 2nd endings, etc. without workarounds. I envision that when you try to tie a note just before the repeat, there could be some sort of setting that lets you tie it back to the start of the repeated section. Something similar could be done when trying to tie into a 2nd ending from just before a 1st ending.
