One of the most challenging tasks working in BIAB for me is controlled pauses between bars.
There are a couple of "workarounds", such as creating a bar with single beat, tempo change and that sort of tricks, but I rarely get musically what I need and ending up compromising.

Request is to be able to simply insert a "pause" without chords, like you would insert a bar into Chord view and simply define it in seconds. Simple decimal view.

Given nature of BIAB programming, sometimes composition is way too tight and needs "breathe pauses" to sound more natural.
