Good to switch or restart layouts?

In regards to avoiding hangups and crashes, would it be beneficial to restart/reset or change layouts?

Some features I'm about to incorporate I can use a hidden layer or use a whole new layout. It just popped into my mind about repetitive scripts (causing a browser warning) and the warning about a script causing slowdown—not to mention crashes and such. Makes me wonder if changing layouts is similar to navigating to a new page decreasing those chances.

Not sure if that makes sense but thought I would put it out there.

I think it would "drain" the same amount of resources for restart and change (as you have to load again a layout) I have not used very much reset and definitely not enough to form an educated guess, but maybe Tom and Ashley can help you...

The hidden layer assets will still be loaded into memory, depends what your memory usage is. It's not a good idea to load everything you need for the entire game into one layout though.
