There will be one last Xbmcremote release, which will include an updated description (in the store) and an updated app with an in app notification to upgrade to Kodimote. But I want to be sure there are no remaining issues before advising all users to update (like the already fixed settings page not being fully visible, and this issue also needs to be fixed, although we both can't reproduce)

I don't know about moving settings (automatically) yet. As it feels a bit dirty to check if the Xbmcremote config file exists and then moving/copying it over. And it aren't that many settings, so the user should be able to enter them again. Unless you have Zeroconf disabled, it that case it would be some more work indeed. Although entering the MAC shouldn't be required anymore. When the MAC isn't known (which also happens on some systems, like OpenELEC) it now queries Kodi (or Xbmc) to get the MAC address.
