Unfinished row undo

[jkiviluo]

At the moment undo will undo the latest change that has been staged (to be committed). If one is working on an unfinished parameter value row, undo will not undo the changes on that row. Instead, that latest staged change will be undone, which is not what the user expects.

Needs some creative solutions, since the current undo stack is used for the commit.
