A Checkbox in the entry editor like: "Draft is ready to post" If you check this box and save the entry as a draft it appears under "Manage Drafts" / Your drafts in another color.
I got a lot of drafts there and some are ready to post, some not. So you could see with one quick look which draft isn't a draft any more and ready to post. Why not just post the entry when its ready? I like to write some entrys ahead and when I got a dryspell I have something to post :)
Would this be much work to change / create as a Plugin?
The only thing I can think of is putting a mark such as "[ready]" in the title, so you can see it is ready. When you want to publish, you can manually remove the tag. I don't think you can currently write a plugin to color the title (unless some javascript wizardry is involved... which in this case is not a bad idea after all)
Couldn't the draft edit panel include a check-box for "ready to publish", that stores just another faked category (same way we keep track of locking comments) f.ex.?
Then on parsing the drafts it would just be querying the drafts and add a special css class to the links that the theme could pick up?
Or would such an approach add too much processing?
Just my €0.02, which probably won't work anyway :P
