1. Global no fly zone checking feature;2. Customized checking items;3. Create some logs for preflight checklist; Pros: It's a genius idea for helping new drone pilots for preflight checking. Very easy to use. It just takes you 30 seconds to get checking done. Cons: Maybe add more customized checking items and no fly zone checking I guess. It would help users more. Cheers!
