- granular control over time scrubbing, show CPU state
- error showing replay div before rom starts
- compiler flags for final ROM build
- coleco sprites need brev
- workermain: split build functions, better msg types
- vcs: INPTx needs to be added to control state
- rename, delete, save as
- sdcc: can't link asm files before c files
- what if >1 file with same name? (local/nonlocal/directory)
- can't upload files already exist
- upload files w/o new project
- what if .c and .s names collide?
- live coding URL
- memory viewer: ROM/RAM/VRAM/etc
