Sorry if this has been suggested before, but I tought it could be nice to have a button beside the “Modify data” in the bottom of the request page, to preview the item's page, before sending the modification request.
I think this is good because:
1) Sometimes you won't notice what you missed, before seeing the page in full.
2) For larger request it's nice to see how it looks.
2.2) Especialy if it's a modification, and not a creation request, since you can edit a creation request after sending it. We can only cancel modification requests, not edit them.
3) Nice for bigger (modification) requests.
Hope that's something to be tought about, at least :)
