Good morning, Kirkburn from Fandom Support here.
We're in the process of enabling a new feature on your wiki: automatic draft saving in the classic editor! We are looking to roll this out across Fandom in the near future, but want to stress test it first and get feedback.
Essentially, this tool autosaves your planned changes every few seconds, so if your browser crashes or you accidentally close the tab, reopening the editor will bring you back to the same place!
You will have the option to discard the draft, and drafts are automatically discarded when you save your changes.
It should activate on your wiki within the next day or so.
If you run into any problems with it, please send a note in to Special:Contact/bug so that we can take a look! Thanks for your time :)
