Great Responses, you're awesome!

Will get the chance to check tonight, thanks! I can not rule out that was just me messing about with the VMs, because I have not noticed something strange afterwards.

Ah, that was what I've been looking for, thanks a lot! Somehow I stayed oblivious of the "Repeater" Item. Might have been quite late.

In the current state (oh, actually that already made it on to the screenshot above), favourites get a slightly brighter text color, perhaps I'll just leave it at that for now, correcting the colors to not be hardcoded. Primary/Secondary text color sounds much more reasonable. Later on, some Items may have additional settings/inputs – I may resort to opening a new Page then. Thanks again, your whole reply is most helpful.

It's basically a slightly modified Version (can't use node request, obviously) of the node.js api and loads of commented out stuff that I tried, plus my user_access_token hardcoded in there. That should at least be configurable (if not replaced with real authentication) before I can show anyone. Other than this and the horrible code quality, I see no reason not to share this. Will ping you, if I get to it – thanks for your offer. Great to see it could be interesting or at some point even useful to someone else!
