The system folders (Inbox, Sent, Trash, Drafts, Junk, Archive) are in a set order. Any folder you create on the same level as those, will be listed alphabetically after the system folders. Any folders you create inside on of those folders, will be listed alphabetically within that folder.
Your email client has the key advantage of allowing the Calendar functionality with GMail, which Outlook doesn’t. But I have NO idea how you could have missed that people would want to be able to rearrange their email folders by dragging them, and also their Tasks which I see isn’t possible either. Makes it pretty useless as a client for me, and until you correct this I think you are losing market share to people like me with many folders to separate out their email. Tasks I find to be less functional than Outlook’s on many levels.

I would then suggest to create a Feature Request “separate post” with the above in it.
I don’t personally need that feature as are happy with the order of the account inbox, sent etc folders, “but as you want the ability to reorder those” then either you create the feature request.
Or @gizmo2501 could change this thread to a feature request at the top.
