Language support plug opens (slowly) multiple popups

[PerfectCarl]

Hello,

each time I use the switchboard app, I forget that a click is enough to launch a
plug (I'm one of these double click user).
Most of the time, this is harmless as my second click is ignored and
the plug is opened "in place".

Unless, the plug launches a popup.
Then multiple instances are launched.

The matter gets worse if the popup launches slowly.
As the switchboard doesn't give a visual feedback on the click event
(like highlighting the icon, for example), I happen to repeat my
 double click over time.
(elementary's speed rot my mind and made me quite impatient :)
As a result I have a buttload of slow popups initializing.

So what are my suggestions?
1) implement a visual feedback on the click event
2) prevent non elementary plugs (ie popup plugs) to be launched many times

Of course, maybe the best course of action would be 3) to implement the ugly
ugly language support as a native elementary plug.
But I don't know how hard this would be, so 1) and 2) are maybe the more
pragmatic choice for the time being.
