I'm looking for this feature too.

Unfortunately it is not possible at the moment for a user to change the order of the lists. This is already on our enhancement list, we can't however commit to a timeline.

The current sort order is;
- Inbox
- [All normal lists sorted alphabetically]
- Sent
- [All smart lists sorted alphabetically]

This would be a huge help

I agree, this would be very useful. Glad to know it hasn't been overlooked. :)

I use leading punctuation and a choice of words (thinking about alphabetical order) to order my lists.

For example a parenthesis (curved bracket) will appear before a bracket (square bracket) and both will appear before a leading underscore. A leading brace [ { ] will push it to the end of the lists.

+1 for using leading punctuation. I do the same and it does the trick.

I add my vote for this capability too please.
