These are great, I’ve been using the accetto firefox images for several years. I was surprised recently when I purchased a $5 VPS and was able to use it without performance issues. I actually like using TigerVNC more with it than NoVNC because the quality is usually better, and it just seems to work better in full screen. Though, NoVNC lets you setup a machine then easily send it to someone to continue or collaborate.
There’s also neko and some other related projects that aren’t completely the same, but slightly better for collaboration.
I thought that the idea of just explaining to instance hosters that they can start user-like scripts on every page might be a good enough plugin system for LemmyUI until there’s more effort into a real plugin system. Users don’t have to install extensions, and people running instances can make decisions for improving the UI.
With a centralized services like reddit, this doesn’t work very well. Though the fediverse allows lots of customizations when it’s related to themes.
