There's also a neovim plugin for those who want to play around with this locally https://github.com/gruvw/strudel.nvim ; it essentially launches strudel in a browser but synchronizes the strudel and nvim editors.
Is there a way (like a CSS rule or something similar) that when you look at the main strudel window, it only shows the piano rolls, punch cards, sliders, etc - but not the code?
Maybe with just the comments? This would be killer, since I have dual displays, and on one I can just focus on the code, the other one can have all the visual stuff.
I'm using this plugin, but having the code twice distracts me a lot (but I prefer the original neovim instead the integrated vim mode inside strudel).
I've only just started playing around with it, so I don't know enough about it unfortunately. You could open an issue against the repo; the plugin owner might be able to answer your question.
EDIT: fixed link to not have trailing semicolon.
