Also some way to read the change log from Minion before updating, similar to how Curse Client lets you do would be nice as well.
Already on our 'to do' list. As I noted previously, however, it will only work if the author uses the actual change log option. If they just put their change log at the bottom of their description page, we won't be able to pick that up and show it as a separate thing.
As for the other request, I'll leave that to the programmers to answer.
