One big issue with voting is that we need to vote on, say, 30 edits adding "X played guitar on a recording on release Y" separately, while in most cases, these will be either accepted or rejected as a whole. Ideally, we would display such edits grouped in some way, and let people vote on all of them with one action, while still allowing them to "unpack" the group to vote differently on some of them if not all of them are actually correct/incorrect.
