Proposed, and implemented, some enhancements (1Mb + 1Mb firmware, resizable jsvars size, ...)

Hi @Pedro,

1MB for save code won't work, as far as I have seen in the code. The main reason is that saved code must be first allocated somewhere in RAM, and we do not have so much RAM :)

I fully agree, it's a waste of space.

At the end it will be a solution that calculates JsVars * 16 byte and add the rest as FlashArea.

Regarding RESIZABLE_JSVARS .....The idea is to leave as much heap free as possible when not needed for JsVars

I definitely will try it, because this is too temptingly :)
