+## Ideas for new software projects
+
+Here I collect sketches for software that I still need to write (or that I
+would like to be seen written by someone else...), and features that
+IMHO still need to be implemented in existing software.
+
+This section can also serve as a source of inspiration for people that have too
+much time on their hands... ;-) Feel free to [[drop me a note|contact]] if you
+should start realizing one of it, so I can update the information here.

+### JOSM: Nice-to-have
+What I would like to see in [JOSM][], the Java OpenStreetMap Editor:
+* Raw diff view of the changed XML data. The current preview in the upload
+ dialog is too simple.
+* <strike>A function to copy a bunch of tags from one object to another. Example: I
+ have a node tagged with `shop=florist`, `opening_hours=...` and want to
+ transfer these tags to the surrounding building to delete the node
+ afterwards.</strike> implemented in [utilsplugin2][]
