I understand your concerns but I want to keep Transponder separated from the integrated Telepathy stuff for several reasons:Telepathy integration doesn't play well with Harbour and I really require this. Depending on Telepathy implementation in SFOS, porting to UT, Plasma, ... is more difficult Jolla's Telepathy doesn't support properly group chats, files sending like it should. Transponder should reach the state of Sailorgram (in the future)
Also if I remember correctly, there is still the closed source UI layer, so even if community implemented all the backend stuff, someone from Jolla would have to do the UI bits to actually make it useful, which is unfortunately very unlikely to happen given similar cases in the past.
One of the features I've been trying to integrate into Saera is the ability to read texts aloud as they come in, or to send them with dictation. Will Transponder have a method to allow other apps to communicate with it?
