Chart editor based on BPM & time signatures for accurate note placement

[shockdude]

The current chart editor is designed around hitting keys as the song plays, which is a very inaccurate method of charting since nobody has totally perfect key-hitting ability. It is very difficult to chart accurately using timestamps alone.
Instead, the editor should support charting based on tempo & time signature, allowing for perfect alignment of chart notes to the music.

Btw this is a fascinating project, great work so far.

Thanks for the suggestion! Indeed that's a very good point and I've been thinking about implementing it, but I wasn't sure about how. Will add this to the roadmap.
