@dobey The app wouldn't need the biometrics information itself, just an event, that the sensor was touched. So the critical information would be protected.
For other use cases biometric confirmation, encapsuled in the middleware, could be an interesting feature, for example to unlock a protected data source or to confirm any transaction.
Where is the component to get this event? The middleware needs this event either?
@kazord Last year a developer has shown in our hackathon, that is s quite simple to exchange the system UI by modifying some QML files. He presented the nice grid style ofr open apps like Nemo Mobile and Sailfish OS instead of the current fan style in Ubuntu Touch.
My hope was, just to modify a QML for the sidebar with a Loader, that loads the launcher app instead of the current sidebar logic. To avoid conflicts with the default system this part could be dynamically controlled as a standard - with any setting or an installed app with specific privileges.
My idea in general is to provide customization of the system in a standard way. Sailfish OS could be a good example for this approach. OEMs like Intex and Jala have used the Standard Sailfish OS with some customization for their market. The idea of a Super App is quite smart. It is a app, that can be called with one swipe gesture. It can be controlled by a setting.
Anyway. If someone is interested to help us with a proof of concept. Let me know.
