Ability for a commenter in the Wishlist to edit their comments.
I run most comments through a spell checker and even Grammarly, but new last-minute thoughts occur, a too-long comment must be edited, and even just through oversight, mistakes happen. Sometimes the results are confusing, or I think of a better or shorter way to say it. But large error or small, it's always embarrassing. And why make life hard for readers?
The software we’re using for Wishlist – UserVoice – does not allow to edit comments to keep integrity of comments exchange. But they allow to delete one comments – so you can copy it, delete and then comment again.
