Hey davidjmillerorg (and everybody else reading this),
Here's something that I think is a great addition to this plugin.
Let's say we have 2 authors: Jules and Vincent and we have set our post interval for 30 minutes. If Jules makes 2 posts, the first one will be published and the other one will be scheduled, right? That's great! Then 5 minutes later Vincent logs in and posts, but his content is also scheduled, because Jules is an a**hole and posts all the time. Now Vincent have to wait from 25 (if the plugin is set to LRA) to 55 minutes only to see his own post and share it to social networks and stuff.
So they sat down and thought about it. Suddenly - a solution! What if the plugin could have different schedule options for different authors. In other words if Vincent haven't posted in a while (let say the interval is set to 30 minutes) and he has no scheduled posts, then if he creates a new one - it will be publish immediately, no matter how many posts Jules (or any other author) has in the common schedule. Later on (less than 30 minutes) if Vincent wants to post again, then his posts is added to the end of the schedule. And so on...
I hope you understood what I had in mind ;]
