Mochi feature request

[Zumh]

Hey Matt I'm a big fan of your mochi app and currently using it for studying self taught software engineering program.
I don't know where to write this message, so I just wrote it here. If this is the wrong place please redirect me to the right place.
I have a very important feature request that may not be possible but I think you should add complete Vim text editing feature on each card. If I try to edit a card, the active is the focus and Vim mode will be enable by option. That way we can use visual mode or block indentation. Also regex for filtering out or edit some pattern matching for bulk editing. Any way, if this is impossible, I totally understand.
