Thx for the feedback.
I’ve certainly switch my brain off when writing this.
The drop down for language is just for syntax highlighting right?
It's slightly weird that a tool for "running scripts" offers to highlight something as HTML or CSS though. Might need to be a bit more specific about the options shown there.
Also, in dark mode, the editor is unusable by default - it's black text on a very dark grey background.
It's just a version 0.2 so there is some weird things like that (list of languages). I will restrict this list, that a good point.
From the settings you have access to other themes colours. Some of them are more confortable for dark mode.
