[GRASS5] [5.7] v.digit

[Hamish]

Hi,

some requests/feedback for 5.7's v.digit:


1) remove vertex:
when there are duplicates, there needs to be some way to select
next/previous line. Otherwise it can be impossible to get rid of
duplicates by hand. GRASS 5.0's v.digit can do this.

        |---------|         what I want to get rid of
--x-----x---------x------>  displayed
        |---------------->  only line it will select with mouse


2) settings/symbology (colors):
yellow is very hard to see on the white background.
Change default highlight color to blue?
Make no default color the same?


3) settings/symbology (colors):
Unchecking box for "Node (2 lines)" & then redraw doesn't work.

It is impossible to track down where area boundaries are open when 
every node is shown! Had to export to GRASS 5.0 to see where the
problem was.


4) Is it possible to exit without saving?
Nice for beginners, as there is no required input= and output=, and 
you don't always remember to make a copy first.


5) XFree86 is using ~45% of the local CPU when v.digit is running. 
ssh uses about another 45% (tunneled X over ssh). Is it stuck in 
some sort of feedback loop? When you click exit, it stops as soon as 
"Registering Lines:   nnnnn", seconds before the menu disappears.



thanks,
Hamish
