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?
