[CodeVisio]

Before walking and running, it should be capable first of standing up.

Screen readers, voice input, etc are additional features one can add once the "core" is done, in future steps.

My issues are basic. How to organize a hierarchy of UI widgets and in a clean way such that it supports features like event notifications, bubbling them, hovering, focusing, mouse capturing, and it is at the same scalable: If I add another UI widgets later (a composition of basic and available ones), it should be done with less efforts and leaving me to concentrate on the new functionalities instead of replicating existing behaviors.

I was able to handle buttons, check boxes and single line text boxes with a custom rendering system I can change at design time. But the hierarchy of widgets, the design of C++ classes, and the event notification are not clean (although working), hence the bells started to ring.
