= touch onscreen keyboard requirements =
none of the existing ones fits our purpose, so create one from scratch

needs someone to implement this, preferred programming lanuage: C ?
* needs to be tied with keyboard indicator to change layouts on demand (https:/
* needs to work with IBus to change layout whenever a different IME is chosen
* get layouts from XKB
* for IMEs we need to produce layouts by ourself
* store the layouts in the ibus packages (modules)
* add function keys, like arrow keys, etc. (configurable)
* detach layout from the actual keys submitted to IBus (i.e. display Bopomofo, but submit Latin characters from US English layout)
* use python-virtkey for emulating modifier keys.
* use SVGs for the keys being displayed
* accessibility
* when user moves his finger over the key, use text-to-speech to tell the user which letter is under his finger
* needs text-to-speech framework [luke]
* needs hints for the text-to-speech synthesizer to tell the user which letter he is dealing with
* use espeak?
