of all the features you mention, except TTS none depend on the app being written in a specific framework as far as I know ?
(and I don't remember TTS not working in e.g. Qt apps for instance - at least I know that I sometimes bash my keyboards repeatedly to stop the damn thing that I opened by whatever goddamn shortcut :D)
This was a direct response to your comment, so I was mainly focused on what accessibility features I use. However, one I missed but I use all the time is being able to control applications using accessibility APIs.
