Zapper: Add "undo" button along with "close" button

[jocelynetienne]

It happens when using Zapper that one zaps out some useful content by mistake. Now that there's a "close" button for zapper, it seems very doable to add also an "↩ Undo" button.

1. Not possible. How do you want uBO to restore something you've just deleted from your browser?
2. Refresh the page. Zapper is a temporary tool for the current page load only.

It is possible for the zapper to keep a reference on the removed element and its parent so that it could be put back. I feel it might be a good feature to be able to undo the last removal at least rather than have to reload the page.

If I'm not wrong, removing the node will also remove the events attached to that node? If so, would putting it back restore those events as well?

[gorhill]

It wouldn't restore event handlers if any, but I still think it might be useful, especially for Android, it's easier to mistakenly remove something.

Does restoring a DOM from Dev Tools also remove listening events?

Maybe it's possible to pretend that the DOM is being deleted as if from a closed dev tools level - Profitable when most events come back (after finding something that works like Ctrl + Z in Dev Tools with events).

The difference is that unlike in Element Picker wherein elements are hidden, in Element Zapper elements are removed.
Hidden elements can be easily restored (unhide), but removed elements cannot be easily recreated because the whole DOM structure of the website might dynamically change, and even if recreating is sometimes doable, in some other cases/websites it might be too problematic to recreate it.
