what is the best way to propose changes to the JOSM default preset?
JOSM is installed on my machine. Is the preset somewhere on my file system and I can edit it to test the changes I’d like to make? Or would I export the appropriate part to a separate preset for testing?
Then, when I know how I want it, can I register on the JOSM website and create something like a pull request? Or rather just a ticket?
The JOSM default preset is inside the jar file/application. The actual XML file can be viewed here: defaultpresets.xml in josm/trunk/resources/data – JOSM . There is a download button at the bottom of the page (look for Download in other formats). Fair warning, it will take a bit of time for the page to load.
