yeah from commonUI the only thing that I use is the stack widget. But its not hard to recreate that either with blueprints.
But the basic principle of how it works has still been very helpful to me. The idea of push/pop widgets from a stack.
Well, I do use the activatable widgets as well. Having them auto-manage focus does save me some work. But like you said, it can be fussy about focus loss so there’s been a few times I’ve had to hardcode some failsafes to manage that. It would be nice to know a more proper way to implement it, but if that knowledge means digging through Lyra for the next 2 months, I’d rather just make a simpler system and keep working on my game :).
