Separate out into multiple .el files

[lastquestion]

I can't handle this giant .el file even though it seems it's common in elisp land. Find out how to make it work so there can be multiple files.

• Will it be a problem for straight, etc.?
• Do I need to build some packaging?
• Maybe wait until I can distribute thru MELPA, then people don't have to manually download
• I probably need a build system at this point
