Oh, certainly. PEGs are good for ideas that are already pretty firmly
shaped but if you're not quite sure, a discussion here is very good.

I agree, and have agreed for a long time.  The question is: when can 
we schedule this for whom.

The problem is that there is a small number of people doing lots
of jobs.

Saying "X" would be nice usually stresses me because it's
difficult to allocate jobs as it is. It would be really nice
if we could start discussing priorities so that it wouldn't
be only my job to keep in mind all these "wouldbenice"ties
and try to think what's so important that it should be done
now by someone.

Only the pure java version?? Why not also GL version?

Well, that can be done by Ctrl-V creating a special flashing object
and mouse motions take it to right or left, or something?

It cuts both ways: for any extra button or feature, 50%-80% of people
will *never* touch it.

I have to say that I dislike this idea. Modes are usually bad, especially
at such a central thing.

Imagine someone who doesn't know a thing about us trying to use it.
"What happened now"? ...

A modifier key has the advantage that you always *know* whether you're
pressing it or not.

A changed mouse cursor shape just makes people feel weird, unless
it's directly associated with something they do.

I'd propose shift-drag for selection... Or mouse button 2.

A different idea: the selection floats at a "clipboard".
When you select a new area you then drag a line out of it, left or right,
and then leave the line and drag the thing from the clipboard to the line?
