UI mars an otherwise good product

For what it is, this app is great, but the UI really makes it hard to use.
1) the region loop/play controls are horrible. Even after reading the guide I have no clue when Im going to pause/play the whole song or a loop after changing regions. I just use the play button on headphones or a Bluetooth speaker now cuz thats actually consistent.
2) This needs either over lapping regions or multiple projects for the same song so I can break down a solo into parts to learn and then loop the whole solo without having to kill the mini regions I worked so hard to create in this UI.
3) The tempo control barely works. If you drag if far left, it will never drag back because the ui keeps thinking youre trying to swipe the whole control. Only way I can fix it is by mashing the thick bar for 100% tempo and even that takes about 20 presses before it registers.

When the UI isnt getting in the way, this app great, but unfortunately the UI is in the way about 80% of the time.
