I found icons for 'delete', 'search in note' and maybe 'open note' (the folder).

At some point the icons for 'add' (the plus) and 'full screen' might come in handy too.

So the missing ones would be:

• Decrease indent
• Increase indent
• Link to other note
• Select font style

It would be really great if you would come up with something. But please don't feel pressured and don't forget to enjoy your trip. Ah and when you're in "Stugi" make sure to eat some "Zwiebelrostbraten mit Spätzle" or (if you don't eat meat) try some "Käsespätzle". Both is absolutely delicious
