Allow you to quickly add and remove TS from any objects selected.
Changes applied to the first turbosmooth in modifier stack.
If you have an instanced turbosmooth modifier and select all objects to which it belongs, script will change its state first.

In v1.1b added:
If you disable modifier in stack (switch the lightbulb off) fist call of the function will enable it. [bug]: the icon of lightbulb in stack will not update unless you deselect and select again the object.
Iterations was limited to 4.

How does it works:
Select and object and call TSSmartAdd or TSSmartRemove function.

Installation:

Throw .ms to your 3ds max viewport or run it through scripts->run...

New category called "custom" will apper in customise->customise user interface...
There will be two functions:

1) TurboSmooth Smart Add - adds or increment ts modifier;
2) TurboSmooth Smart Remove - removes or decrement ts modifier.

Bind both to shortcuts (Ctrl+PgUp/PgDown recomended) or place it on toolboard/quadmenu.

Thanks for using my script.
