Okay, it’s good they have the open source because if you rewrite the Chrome extension you can get it to load in under 100 ms after you click the button. If you use the standard Chrome extension you’re not having that happen on an M1 Max. Their stuff is far too heavy. Full JS framework to display a small box.
In today’s day and age I read the OP as saying that threw an LLM at the extension repo and had it reimplement/improve upon for a private fork of theirs.
