The message "Changes recovered. Your unsaved changes have been automatically recovered." can get easily missed. During the second or two that it is shown, you can just looked away from the screen, and missed it. A longer duration would still not fully fix it, as people can be away for longer periods. This is a problem, because people can publish edits they don't want to to.
Suggested solution:
Make it dialog instead, that has to be dismissed. This way, the message cannot get missed.
Hi @Distelfinck, thanks for taking the time to report this!
I had to search through all code bases to find out that this message is about VisualEditor. For future reference, please add a more complete description to your reports and provide clear steps to reproduce. Thanks!
I don't think it's good to block the user from proceeding using a modal dialogue in order to let them continue editing. Blocking users from proceeding using modals should be used only when strictly necessary.
It might be a good idea to make the dialogue more persistent, by possibly having it remain there until the user hovers over it or interacts with it in some way. Then again, that might make it annoying.
