When We Getting an UNDO Button?

Anything that doesn't fit into other topics goes here!
Hi guys, so I have version 1.0.2 installed for Win 32, but alas, I see there is still no undo button? Has there came one since? Wouldn't it make life easier?
undo will be possible in piano-roll in upcoming release 1.1
No scedule for general undo.
You can upgrade to 1.0.3 btw :)
