2389	Style sheet system to visually enhance map data for editing	Vidar Gundersen	team	"I'd like to see extended support for custom display settings.

The motivation for this is to easily change the display to aid map editing for different purposes, e.g. mapping roads, urban areas, country side, hiking, cycling, etc. Well mapped areas have so much data now, it will be useful to filter the view for different purposes, and be able to quickly switch between those.

A quick thought on how this could be:
JOSM can construct a submenu from files found in a given folder, e.g. ~/.josm/styles/, where it lists all available mapstyles. The style files can be in a format similar to what used for mkgmap and css.

<pre>
highway=motorway & highway=trunk { color=red; width=10; }
highway=footway & highway=path { color=green; width=2; line-style=dotted; }
highway=* { width=1; }
amenity=parking { symbol=img(http://example.com/parking.png); }
</pre>
