Nice idea, I think @slobberchops has done some similar coding for his own purposes (to find accounts that met certain parameters to vote on), he may be able to contribute some ideas.
I've sent an HBD tip to you via keychain. I would have used the tip jar tool but it requires me to create an account, I can see the value in that for non-hive users, but I don't want more accounts 😂.
Now you mention it, I've seen one of his posts. He even shared one of the scripts he uses.
Thanks for the generous contribution! You shouldn't have to create an account for the tip jar. It uses Keychain as well.
Okay, I've just checked. I can't see where tip jar refers to keychain? Sorry if I'm being dense!
If you add your username in the from field, your Keychain browser plugin should popup when you click on send transaction :)
