I will think about tree+entry (d.dm window displays also something
like legend (color(s), icon,..) and so tree should contain these items. 
Changing color would require 3 clicks instead of 2)

I decided not to use meta-description because only few types of maps
exist (raster,area,line,site,dbsite,label) but with very different entries.
(I want add for example option for vector categories: all,
category, postgres, dbmi  and change entry fields dynamicaly according to
selected type)

Yes I'll add CELL driver. I want also add Plot (ps.map).

Yes I'll add chmod to Gmakefile

d.dm is not in list yet, I'll add soon.
