No, Miqobot supports only single jump to fly method.
This is stated directly at our website under Quick Setup:
1. Character Configuration -> Mouse Mode (not Gamepad Mode).
2. Character Configuration -> Movement Settings -> Legacy Type (not Standard Type).
3. Character Configuration -> Flying Mount Takeoff -> Auto: Take off on jump.
Double jump to fly is considered but not planned in the near future.
At the moment we focus on fully functional upgrades for Stormblood, but we will try to include additional research into development plans later.
Thank you for your request!
