Strongly agreed. In fact, k9 needs a very long stack of undos. I just accidentally lost a lengthy 2 hour composition to a family member. I have no idea how it got deleted.
This happens so often, i usually remember to draft the message in a different app, then paste it into k9 immediately before sending.
I’m on the verge of abandoning k9 due to this horrible accidental delete “feature”.
Either change this accidental delete function, or create a long undo stack.
