When starting a Play Solo test, the delayed loading of plugin widgets will cause the widgets to capture focus when they are created. This means when I start pressing character movement keys (WASD) or using tools (numbers 1, 2, 3, …) they will be given as input either to the plugin widgets (e.g. searching for wwwwwwwwwwwwwwwwwwsasssssssss in Find All / Replace All widget) or to studio as a whole (selecting the Select, Move, Rotate, etc. dragger tools). I just want to test my game – stop doing other stuff, please.
In general, my opinion is that plugin widgets automatically capturing focus when the widget is created is a really annoying behavior that should just be disabled everywhere IMO. Give plugins an API to capture focus when they know the user really does want it, otherwise the widget should not affect the user’s focus state at all.
