Regarding history, right now we have a history browser implemented as a Calypso plugin, that is open using context menu => history or the little box button on the top right of the method pane (second button from the left in the picture):
That button will nowadays only be shown if the method's package is linked to an iceberg repository.
Once you click it, you will have the entire history of the method.
With the possibility to install that version of the method (among others).
Now, regarding the recovery of deleted classes/methods, have you tried the repository browser?
Go to Iceberg, right click on a repository and select "Repository".
You can there select a commit in history and then in the tabs below see the diff between
��- your current version and the selected commit
��- the selected commit and its main parent
Of course any of these can be improved, but if you have concrete requests, it is much easier :)
