Undo button for Zotero actions

Edit > Undo seems not working. For example
I deleted an author but I didn't want. Undo.
I deleted a tag, but I didn't want. Undo
I moved an item between collections, but that movement wasn't what I desired. Undo.
I removed an item from a collection, but I was wrong. Undo
I renamed/moved/deleted a collection. Undo.
I sent an item to trash. Undo
Merged two items. Undo

And so on. The only thing which couldn't be undone is empty trash, or recovering an item which was deleted permanently from trash.
