The “Reset” button reverted my preferences to “Internal Preset” (resource://data/defaultpresets.xml). However, this setting does not produce any working presets either. I can’t figure out where this “resource” location is supposed to be – there is no “data” folder under my C:\JOSM.
Questions:
Where can I find a working set of presets for higways etc?
After I customize these presets, how can I tell JOSM to use the file on a local disk? (Would something like file://C:\JOSM\mypresets.xml work?)
Btw, I found out why the presents had disappeared:
The “Presets” menu option is always grayed out when there JOSM has just started and there are no data layers (this seems odd).
The toolbar buttons for preset folders had disappeared when the “better” preset site vanished, and I had to redefine them manually (the end result is better than the original, of course).
I also found out that the “better” presets were not so good; the standard presets are more complete (only highway=secondary_link was missing).
