Coming from Apple mail and liking Missive very much, I do see one thing I sorely miss: the ability to combine multiple filters into one.

For instance, I usually used 'Unread' OR 'Flagged', which gave me all emails that were either unread or flagged. Right now in Missive, they exclude each other, but I want to combine them :)

The way to do this would be to add the option to use 'and' and 'or' dropdowns with every filter, so you can decide if you want to combine them or not.
