I had to rethink scheduled posts a bit to better account for when they were being set (future dates) so as not to completely mess up the section numbering and to provide an easier way to perform checks on whether there were any scheduled posts in the table.
If there are any scheduled posts then a new clock icon will show which will link to a new 'Scheduled Posts' page where I can edit or delete them if required:

A new column has been added to posts table – a UNIX timestamp – to make it easier to check if there are any posts 'newer' than now.
I need to finish the Scheduled Posts page today and then the feature should be complete.
