A really cool feature to make devex easier would be a Wizard that helps uploading metadata for programs.
What do you want to upload?
IDL
-> Security
Do you want to add program version number to your metadata?
Security.json does not exist, do you want to create one?
Do you want to use a multisig?
What is yout multisig address?
-> Export base58 transaction
etc
...
Also helper functions for upload IDL and Security as a standard would also be good?
