RE: PLEASE PLEASE an Undo
Hello,

They are 2 big issues with undo.

1) What do you undo? I can type a command line command that, for example, overrides a file (AFiles("a.png"):= G0). What does undo do here.
Of course, this is an extreme example, but just something as simple as A:=0 is not a simple thing to undo...
I can type a command line that creates and override a whole program!

So, doing a simple undo that works in the home command line is already quite complex. I guess I could take a snapshot of the memory and save it... but that takes a lot of RAM!

2) The point above was just about undo for the home screen. But undo means different things in every view of the system. And would need to be implemented in every view of the system! Although some places could share a generic code, in most cases, it would mean a LOT of SW development to get a good working undo.


More than anything else, I think that these 2 points are why UNDO is low on the radar. It is hard to implement, and it takes a LOT of time to implement. This makes it a function which, while having a high value, also has a high cost, giving it an overall low priority factor.

Note that these statements are in no way "forward looking", just my personal musings. I would personally love to have Undo on Prime.
