Improved filter

[Hedaja]

After I read a few discussions about more and more detailed mapping and its probelms I wanted to ask for an improved filter for JOSM.
In areas with high detail it's sometimes really hard to get behind all points and lines on your display (Even for advaced mappers). I think this is a problem for a lot of new contributers.

At the moment you have to know exactly whitch tags you want to filter.
Maybe it would be good to have tree with ever detailed tags.

You could click a box next to it to activate/deactivate sertain things. If deactivating highways is not detailed enough you could go a level down and deactivete only streets or another step dwon and just deactivate primary's.
