Problem: The "suggested edit" tab is useful on mobile of Wikipedia, but it would also be incredibly useful on the web version.
Proposed solution: Add a "suggested edit" area into the web version, perhaps in the contributions page or something like that. More things could be added as well, such as CS1 errors in citations.
Who would benefit: Mostly "Gnomes" who spend a lot of time adding captions and title descriptions.
More comments: This does exist on the web version, but it is made specifically for newcomers, along with the fact that it has the "newcomer tag" when you look at the edit. I do believe that this should be implemented for long-time users as well who don't want to browse until they find a random problem. I think that this would further encourage and promote things like fixing CS1 errors, fixing articles that have multiple issues, etc. if it is a visible and easy-to-find section in Wikipedia.
