working well it could be quite interesting for desktop app development, as suddenly you could use high level languages and portable UI toolkits but with the sort of startup time, performance and memory usage you'd expect from native apps (modulo binary size which is still quite large). If you want to use HTML as the UI then you can use the Chromium Embedding Framework, which would give you an Electron-like experience but with many more available languages: https://hydraulic.dev/blog/13-deploying-apps-with-jcef.html For a Slack competitor like Linen it would make more sense to use web UI because of the video calling/WebRTC stuff. OTOH if you don't care about that, it'd be (imo) easier and more direct to not use HTML. Proper GUI toolkits give you a lot of stuff out of the box like virtualized list views which HTML still doesn't; useful for scrolling over huge datasets like chat logs. I've been using JVM GUI for years for various tasks. It was appropriate for Bitcoin tasks because it's immune to injection attacks, because you can run everything locally with P2P protocols like the original Bitcoin app did, it's portable etc. Also I learned GUI programming decades ago and find classical UI toolkit concepts like VBox, HBox, StackPane, TableView etc more intuitive than HTML.
