Undo for Deleting a Command Block

[reform-chipper]

As the title says. Currently when a command block is deleted, there's no way to bring it back. There also isn't a confirm dialog box.

The broader goal is to have something like a Jupyter Notebook for shell commands.

Simple example of this vision:

I think a confirm for this might be annoying. My thought here is to provide some small window of undo (maybe 5 seconds). So, if you accidentally delete a block you have 5 seconds to "undo it" and it will come back. This can be implemented by just deferring the actual delete for 5 seconds (although we'll visually remove it immediately). For the first cut of this feature I'd also only allow one item to be "undone".

I know this isn't a fully general solution, but would this solve enough of the problem for you as a first pass?

Yes, that would certainly be better than what we have today. Maybe create an issue to implement a more robust undo system later once there's nothing better to do?

You're right, a confirm dialog would probably be too intrusive. It might only make sense without the undo feature, because the action is irreversible.
