"Move to folder" should remember most-recently/commonly used folders
Being able to quickly filter and sort away messages is important. Similar to the previous version of Outlook.com, the ability to "Move" quickly to your common folders is super important.
In lieu of this LRU-cache of folders used when moving messages, it would be more accessible to have a "Show all" folders option; right now the only way to find other folders is to actually search for them.
As an example, I have a folder called "Purchases", but with the new Outlook experience, I'm finding myself deleting my transaction receipts instead of taking the time to click Move, type "pur" for Purchases, selecting it, and moving along.
The Triage team has this in their sights :)
