This looks great! I have been recently using 1Password as my ssh-agent, which means my SSH keypair will always be available on all devices where I am logged into 1Password and can blog on prose.

Questions after having used the product for 5 minutes:

1. Do you have plans to allow for customization? For, I want to get rid of italics on the date and be able to add menu items.

2. What happens if I `scp ~/blog/file.md prosh.sh:/`? Will the previously-uploaded content remain online? Perhaps more of a scp question? This is my first time using the command.
