various bugs, proposals, and what-have-yous regarding the chart editor

[thersgo]

now, i could make these all into their own separate little threads, but

1. many of these are quite small by themselves
2. are all related to the editor and (mostly) its ease of use
3. this isn't that professional (yet) anyways

that being said,

Thego124's list of nitpicks and problems:

bugs/problems (in order of perceived difficulty):

1. ~~metronome seems to use clap.wav~~
2. ~~editor doesn't have a lower resolution bound afaik~~
3. ~~white notes don't get inverted on the timeline when selected, like how other colors do~~
4. ~~song continues playing after exiting from song's offset calibration menu, plays alongside menu music / editor preview~~
5. ~~ctrl+space~~ (needs a different keybind) (playback from start) doesn't work ~~for me~~

nitpicks and wants (in order of importance):

1. ~~auto-select on creating new note~~
2. ~~in-editor way to change song difficulty and approach rate~~
3. softer hit sound (being worked on)
4. given the visual constraints, multiple tracks/timelines seems like a bad idea, but there should be at least some marcation for when there are multiple notes on the same beat (# instead of a letter?)
5. ~~either:~~ ~~* ability to select and edit multiple notes at once~~ ~~* or commands for selecting and editing notes, which might be more reasonable~~ ~~(repeatedly pressing [down]; e; x; [esc] to change the color of a bunch of notes gets tiring quickly, especially when wanting one of the later colors)~~ (new commands done)
6. ~~actually, x and c don't do anything by themselves afaik, why do you need to press e before them anyways?~~
7. ~~on-screen cheat sheet (maybe even a changing one if you do program the previous one in, so it shows different notes depending on what's selected)~~
8. ~~duplicate note: press a button, copies the selected note onto the same pos. and time, and selects it ( as per 1) )~~
9. ~~better made chart data files: sometimes, you need to edit them manually, which means it's annoying when it's all one line~~

Missing ones that still haven't been done:

• Softer hit sound
• Show different symbols when multiple notes are on the same exact beat
