BPM control for automatic speed adjustment in practice mode
When speed increases in percents in practice mode, the increase gets larger when the speed increases. I'd rather have it so that I could control the speed increments by BPM. For example, increase the speed always by 3 BPM. This way the speed increase is less dramatic and frustrating than it is currently. Now I need to manually adjust the speed, which is really difficult to do accurately (there's another issue about that).
