UI: Ability to refresh inbox by "pulling up" (or add a Refresh button)

I have OR installed as an "app" on my phone. If I go into an Inbox conversation there is only one way to refresh that page -- by scrolling way up (to reach start of conversation) and then "pull down" the page to trigger the refresh. Not very convenient when conversation is couple of screens long -- having to scroll way up every time you want that page to refresh.

... or reverse the order of messages (so that most recent ones are at the top)
