Problems with SMART; you cannot free the plugin when smart is open..
|
|
Therefore, loading & free-ing plugins per script run is not an option.
|
|
Assigning a TMPlugin per Tab might be a do-able solution, but will still cope with the SMART Problems..
|
|
So the question is: Plugins Per Tab,Per Run or Global?
