That's a nice idea. Shouldn't be too difficult, as I already have the
code which finds the group of a given stone - used by capture algorithm.
Right-click already is used to remove a mark. I think double-click makes
most sense. Single-click adds mark on single stone (as it already
works), double-click adds marks on whole group. Same with right
single/double-click, remove mark from single stone or from whole group.

There are a couple of markup figures in standard SGF which come close to
your suggestion:
AR - Viewers should draw an arrow pointing FROM the first point
TO the second point.
LN - Applications should draw a simple line form one point
to the other.
Some more, see http://www.red-bean.com/sgf/properties.html
None of those are supported by gGo nor glGo. I think RubyGo and SmartGo
support these. I'm not sure if I should support those properties. Many
SGF editors don't display them, which reduces compatibility. On the
other hand, the fact that glGo doesn't display them also reduces
compatibility...
I need to look at some other editors to get an idea what can be done
with these figures. I must admit, it sounds a bit useless to me now.
Maybe if I see it in action it becomes clearer.
Free-hand drawing sounds like fun. I suppose it's a major pain to fill a
larger area with the same mark in glGo, as you'd need to click on each
point. Actually, if you keep the left mousebutton pressed down and move
the cursor over the board, it could just keep drawing marks. So instead
of click - move_mouse - click ..... just click & keep pressed -
move_mouse. I wonder if this would also work in online reviews, but I
guess that would be too much mess as you'd keep sending lots of "set
mark here" commands to IGS.
I think this could be done without too much hassle, but I wouldn't
consider it top-priority now.

Will check this, thanks.
