If anyone uses VSCode, I have put together a VSCode extension to support MMBasic. It's not 100% complete yet, but I think it's close enough to be usable. Please try it and let me know what's missing or what you would like changed. I'm also very receptive to pull requests if you would like to like to contribute. Thanks!

Great minds....

You could have a play with this one too.

mmbasic-support-0.0.7.zip
Syntax highlighting for MMBasic commands, functions, types, numbers, strings, comments, subcommands (e.g., Sprite static), and PIO/GUI/etc. sub-structures.
Folding/indent rules for MMBasic blocks (If/End If, For/Next, Sub/End Sub, Select/Case, etc.).
Snippets generated from the command set for quick insertion.
Theme: “MMBasic Editor” matching PicoMite color scheme; numbers green, keywords cyan.
Serial console: opens a terminal on a chosen port, auto-reconnects after PicoMite OPTION/restart drops USB CDC.
Uploader: “Send To PicoMite” (Ctrl+Alt+U on Windows/Linux, Cmd+Alt+U on macOS) uses AUTOSAVE over the selected serial port, with configurable baud and line delay.
Cross-platform packaging: single VSIX works on Windows, macOS, Linux; serialport uses prebuilds or rebuilds if needed.

Quote ## 1) Install the VSIX
- In VS Code: **Ctrl+Shift+P** → “Extensions: Install from VSIX…” → select `mmbasic-support-<version>.vsix`.
- Or terminal: `code --install-extension mmbasic-support-<version>.vsix`.

## 2) Select language & theme (one-time)
- Language mode: click the status bar language indicator → choose **MMBasic** (or Command Palette → “Change Language Mode” → MMBasic).
- Color theme: **Ctrl+K Ctrl+T** → choose **MMBasic Editor**.

## 3) Upload shortcut
- Focus an MMBasic file and press **Ctrl+Alt+U** (Windows/Linux) or **Cmd+Alt+U** (macOS) to run “MMBasic: Send To PicoMite”.
- Pick your serial port (e.g., COM3). Adjust in Settings if needed:
- `mmbasicUploader.baud` (default 115200)
- `mmbasicUploader.lineDelayMs` (default 5 ms)

## 4) Serial console
- Run “MMBasic: Open Console” (Command Palette or command list), choose the port. A terminal tab opens.
- If the PicoMite restarts (e.g., after OPTION changes), the console auto-reconnects and stays open.

## 5) Notes
- The VSIX is platform-agnostic; use the same file on Windows/macOS/Linux.
- If `serialport` needs to rebuild, ensure build tools are present (Windows: recent Node.js usually has prebuilds; Linux: build-essential python3 make; macOS: Xcode Command Line Tools).
- To update, just reinstall with a newer VSIX.

## 6) Quick reminder
1) Install from VSIX
2) Set language: MMBasic
3) Set theme: MMBasic Editor
4) Upload: Ctrl+Alt+U (Cmd+Alt+U on macOS)
5) Console: “MMBasic: Open Console”

Maybe Picom could be integrated to support full backup and restore of a picomite …
