[GRASS-dev] d.vect: remove llayer parameter

[Martin Landa]

Hi,

I wonder what is the reason for existence of `llayer` parameter in
`d.vect` module. I would guess that it's not reasonable to display
features (shapes) from `layer` 1 and cats/attributes from `llayer` 2
at the same time? You can display features from all layers
(`layer=-1`) and to display only labels for features from eg. layer 2
(`llayer=2`). I just wonder if it's not too big price, probably it can
be source of the user confusion. Why `d.vect map=map layer=2
display=cat` still displays categories for layer 1? And so on.

My suggestion is to remove `llayer` parameter from `d.vect` module.
The paremeter `layer` would be used to select all display types -
shapes, cats, attributes.

What do you think? Martin
