Hotkey mapping issue
From the default hotkey settings - map 'move pitch up diatonically' to the up arrow key. It said that was already assigned to something to do with guitar tabs, but I went forward anyway.
It didn't make a difference, as the up arrow key was still assigned to 'move pitch/selection up'. This also happened to the pitch down hotkey.
Just a small thing - but really one hotkey being assigned to two functions at once shouldn't be possible at all.
