hi @keyvan-m-sadeghi would you please give an explanation about what happens after clicking Undo and Redo?

@mehdibalouchi OptionsBox is a dynamic box, its options change based on the current context. When a message is selected for example, it offers the option of run again, much later on we might explore things like reply when we figure out whether such semantics exist (based on user input).

When nothing is selected, undo and redo seem like what the user would expect. I'm still not sure about the TFx side of undo and redo design. I'm very much in favour of not adding any magic; undo and redo would be normal commands that are associated with these buttons if present. Implementing general undo and redo is a well known science, see the redux version for example.

On the other hand, more complex application logic, especially those involving side effects, might require more fine grained control in a per command setup. Say, a command updates a record in a database, general undo would not address this use case.

To summarise, it's a WIP on the TFx side, though the GUI can assume it is a given.
