Mira going to have more sentences so the conversations going to be better. If you want to speed that proccess up you have to post some sentences which Mira don't know here:
Mira still has "Sara" in some sentences. Our database is quite big so we have to change it but this gonna take a while.
The update to "Mira" was very buggy and please update until you have 1.5.2
In 1.5.2 German and French won't work. German because of a bug and French because we still don't have the database for French.
Troufiniou is working on it...
Everything except the German Language is fixed!!! Better design: Disabled Overscrolling and ScrollBar
So have fun with Mira and ask questions if you have.
