The suggestions are to have the three optional entry points (sole connection to raiden) as three prominent but not too large at the start screen.

Each leads to a configuration screen that enables the connection, when possible.

We agreed the subject needs to be researched further as to which best ways the implementation will go.

All related UIs are implemented as a first version. There might be future attempts to improve them.
