Allow Developers to Delete or Archive Old Extension Versions
When an Extension goes through constant improvement cycles the Extension versions start to pile up on the developer dashboard. There doesn't appear to be a particular order in which the versions are displayed so it becomes a tedious task to find the latest one just by looking through the small semver text on the thumbnail.
At the same time, I also suggest adding a function to undo deletion, because I have encountered such a problem. After deletion, I can't find the button to undo deletion.That means my extension completely disappeared after being deleted by mistake!!
