I'd like to add scheduled transactions functionality to my chrome extension, but I don't want to ask the user for password input every time a scheduled tx is sent. My idea is to create and sign transactions then save them, and then send them when it's time.
I'm aware that a transaction must include a nonce, and if no transactions are sent in the mean time, the nonce shouldn't be a problem. But what if I wanted to send transactions after SIGNING the scheduled TX but before SENDING that scheduled TX? For example could a TX with nonce 2 be sent after a TX with nonce 3?
