[REQUEST] Continue PR #471 or start from scratch ("delete" feature in UI) #579
Description
This issue continues issue #436 and pull request #471
I started implementing the "delete" feature in pull request #471. However, there has been an issue with defining a function. Since I couldn't find the roots of this problem, I couldn't continue to implement it. I suggest starting the implementation from scratch since it can help to avoid the problem. Alternatively, you can continue from PR #471 (There are several useful suggestions from @jschlenger that may help)
