Explain the problem as you see it
I have many search nodes for supertags - especially for tasks. Sometimes I accidentally remove the supertag, which removes the node from the search node. Because undo doesn't work, I need to remember which node it was to re-tag it - otherwise, it's lost "forever" in the graph.
Why is this a problem for you?
I forget some of my tasks.
Suggest a solution
Ability to use undo for supertag additions and removals.
