I use OsmAnd for note-taking: @M!dgard/diary/391761

In OsmAnd you can even make audio notes if you enable the “Audio/video notes” plugin.

In Configure Screen, you can enable a custom shortcut button so you can make a note fast.

Update: I didn’t hear back from them, alas.

Update: the climbing gym now has 69 tags (nice) and so has third place in the category of “nodes/ways in Belgium with the most tags”.

The multiple panoramax:* tags at the climbing gym, shouldn’t they all be values of the panoramax tag and divided by a semi-colon?

The number suffix scheme is also established and documented on the wiki. Values (and keys) in OSM cannot be longer than 255 Unicode characters. While in this case concatenating the values gives only 147 characters, an object with 7 images or more wouldn’t be able to fit in a single tag’s value. The authors of the editor software with which the images were added, decided to go with the number-suffix scheme.

SherbetS: yes, that would be even better. Changing the preferences file while JOSM is running does not work, though. (Hence the check at line 25 to avoid nasty surprises.) Let me know if you find a solution!
