Another very minor topic:
In v3, when I close a script, then do a right click, the script will repeat, using previously altered options from the dialog region, upper right corner.
In v4, after a script is closed, right click repeats the script, using original options.
Maybe a minor .ini setting?
EDIT, I may be PARTLY wrong in the above statements :-) (I'll do some more testing.)

ps, got a grid of Truchet tiles to work. (Script still needs some work.)
v4 is near instantaneous.
v3 is quite slow, due to .js as previously explained by MG.
