Add a priority number to each status, so that higher priority will get shown at the top while lower ones at the bottom
I presume this is for Forms?
Yes it would be useful if you wanted to sort through it in the StaffCP Submissions tab, otherwise you can just create an "Options" field called "Priority Status" then as options include what is required.
Sometimes we read a submission but won't attend to it straight away as there is something more serious/important to act on, although being able to sort it out from the StaffCP Submissions that would be awesome.
Just a food for thought, most players would by default want to set it to High Priority - that's just how they operate.
