- Make GRFMerge aware of DOS/Win difference: trg1 vs. trg1r
- Build DOS/Win maps in GRFMerge
- Make .nfo pseudo-sprite format more versatile:
  * no lengths, instead line-continuation with backslash-cr or backslash-lf
  * allow hex, dec, oct postfixes like assembly (40, 24d...), default hex
  * allow byte, word, dword and string values (W:4, D:60d, "Hello there")
- Finish linter:
  - Varaction2s (variable ranges) (?)
  - Value validation in action 0s.
  - Multi-pass linting
  - TextID usage
- Split/combine action 0s and 4s.
- Split(?)/combine action As and 12s.
- Provide better interface for translation. (?)
- Command line arguments to install/uninstall context menu support.
- Beautifier options:
  - Convert action Cs to comments (?)
  - Eat all comments, not just messages (?)
- Config file (!)
- Auto-correction:
  - Action 7/9 num-sprites if it jumps to or past EOF.
- Multiple backups
- gcc-style output (file:line)
- NFO version 8
- Word sized vehicle IDs (A3, A4, more?)
