Where can I find my pending/approved/rejected suggested edits? (a bit like the Flagging Summary page)
I think you mean this, your "Editor Stats":
It's displayed on the suggested edit information page for any of the edits you proposed. Just use your profile's "activity" tab to find your last suggested edit, and open that post. Underneath it, there will be a link to that post's edit history; click that.
Then, find your edit in the edit history, and click the "suggested" hyperlink:
In the suggested edit page that appears, scroll all the way down to the bottom and check the "Editor Stats". It will show the number of edits that you've had approved, the number of edits that you've had rejected, and a list of your recent edit suggestions.
However, it doesn't show pending edits. These are not available for you to look at.
