All nice names! ‘ZettelPlus’ sounds like an app I would definitely try out @Dor 
@3mbry0 I didn’t know that about the frog. I’m looking forward to reading more too
@KaneDodgson, I want to work out of one vault, but right now I have a few attempts lying around where I tried out various workflows/plug-ins. I’m just starting a course at university and need to settle down into a permanent system even if it’s a bit rough round the edges to start with.
Wiktionary’s etymology of Zettel has given me some inspiration, maybe I’ll call mine ‘Fragments’ 
Early Modern High German zeddel, zedel, from Middle High German zedele, zedel, a loan from Italian cedola, from Medieval Latin cedula, schedula, the diminutive of scheda, scida (“strip of papyrus”) ultimately from Ancient Greek σχίδη (skhídē, “splinter, fragment”). Cognate to Low German Zeddel, Palatine Rhine Franconian Zeddel, English schedule.
