no:

r.colors map=Gujarat rules=terrain

the color= and rast= options are two different ways of setting color 
tables, using all of them at the same time does not make sense (maybe 
the module should actually complain about this ?).

In case you did not know: this is vector data.

Yes, as mentioned earlier on the list, creation of locations at startup 
currently does not work.

I don't think you can as it is probably for the old gui (d.m).

No, these are commands for the command line. But you cannot use them in 
wingrass as they depend on the old GRASS monitor display system which is 
not available in the wingrass gui (gis.m - GIS Manager).

Currently you cannot use any display commands from the command line if 
you use the GIS Manager GUI (this is true for *nix as well).

All of these commands are now integrated into the gui.

To reproduce this example:

- click on the "Add vector layer" button
- click on the vector1 label

Beneath the layer tree, you will see appear the vector panel.

Fill out the relevant fields (e.g. "Vector name", "SQL query", etc)

If I have the time one of these days, I might make some detailed movies, 
but not now.
