How to Uninstall Cayenne

@bestes, seems good, but with a small reserve: will the option “uninstall and do a new install” create a new identifier or redo the the previous installation ?
I think keeping the identifier is better, allowing users to redo an identical installation without loosing all his parameters. i.e.: if my SD card crash, I can easily retrieve my dashboard without having to reconfigure everything.

Typing this, I realize something: you need a third option: redo the previous install of Cayenne if it is not already installed. Do you think it’s possible ?
