#107 add watch /debug pane (visual feedback)

[Lieven de Cock]

Hello,

Suppose : no watches added yet, so clean start, and the
panes at the bottom are CLOSED (compiler output only
visible when needed, or manually closed).

Now double click on a variable, press F4, or by right
clicking and choosing and watch. ===> Did something
happen ????
Yes, the watch was successfully added, but the user
get's no clue at all that this went ok.

I would suggest that from the moment a watch is added
the debug pane is shown, cause their the user can see
that the watch was indeed added.

What do you think ?
