CTRL-Z + CRTL Y Features: How much do they value?

[MlinMMEX]

Can you imagine the value of being able to "undo" your last action (CTRL-Z) in MMEX, and "redo" it again (CTRL-Y) if needed?

Every time I make a massive transaction editing, I make a backup before.
Every time I prepare an importing, I make a backup before.
Every time I check a report and change state to "Reconciled", I make a backup.
...
And so on...

Well... MMEX would be a no-fear-to-use financial tool if these actions could be easily reverted.
