I use it as a daily driver with few if any problems, but I'm on macOS. Maybe their Linux support is particularly crappy?

There are a lot of subtle bugs. I'm on macOS too, but perhaps my workflow is unusual? Every time I open it, I find small bugs. There are so many features that it's hard to maintain them, I guess.

For example, a lot of disable buttons do not actually disable stuff. They just hide it from the UI.

Yep. Many issues are Linux only. And even with the issues it’s still more pleasant to use than vscode/ium.
