BACK: yes. as far as you do not want use a button for escape, BACK action should be the last option for each submenu. I can work on Menwiz in order to implemnet an "immediate" mode, that is any change is immediately consolidated, with CONFIRM button the only way to go back. But the code changes are not so easy ...
Unfortunately I can associate an action only to a menu node, not to a list item ... that is memory consuming, I know...
The good new: I found many serial debug tracing statements. That is consuming quite a lot of memory. Deleted. Some minor changes to the code: 180 code lines affected just to spare few bytes ....It' a dirty work, but someone has to do it ....
