[Feature Request]: Simple syntax highlighting for comments in prompt or other windows

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

In case I forget later, using comments instead of deleting prompts, is the only way to experiment. But it can get a bit busy and difficult to find certain pieces. This can be mitigated by lots of breaks and spaces, but I'd rather really like to tell at a glance which prompts are actually active at any time.

### Proposed workflow

1. Comment is made
2. It's green.
3. Profit.
