Re-opening an editgroup for editing after submission is non-obvious

It was not obvious to me how to un-submit an edit group after submission, when I realized that it could usefully contain another edit.

I understand now that the [Edit] button on the editgroup summary page can be used for this purpose, but that was not obvious to me. This edit button remains even after the editgroup has been applied, which also seems strange to me.

I suggest that the descriptive text for this button says something like "Re-open this editgroup for changes, removing it from the submission queue if necessary" or something to that effect.

Start by locating the editgroup summary page and the Edit button mentioned in the issue. Update its descriptive text to explain that it reopens the editgroup for changes and can remove it from the submission queue, then verify the wording for editgroups before and after submission.
