I have 13 draft posts. If I create a 14th it is not saved. If I delete a draft post I can save a new one. It 'feels' like I can only have 13 drafts.
I want the ability to have unlimited draft posts.
Even better I'd like to be able to set an automatic publish time. I use building a collection of drafts so that I can easily maintain a publishing schedule when I am travelling and may not have access to the internet at 'normal' times
