Hi, I see undo was added ~6 years ago, however, it is still disabled by default :( The lack of undo can easily be the top priority issue for the users.
>From what I understand, the current implementation is to build a global history across all test plan elements. It does not feel right, because the test plan is often a mix of loosely coupled items (e.g. different thread groups represent completely different test items), so it looks like undo/redo should be per-element rather than global. Just in case: IntelliJ IDEA seems to implement per-file undo/redo, so ctrl+z (cmd+z) reverts actions in the current file. What do you think if we make undo per-element? Vladimir
