Edit queue is full:
Too many pending edits:
Coloured link without alert box:
Numerous times when I click on the edit link on a poorly written question, frustratingly, the suggested edit queue is full, or I have reached my edit limit.
So I created a simple user script that will detect when the edit link is disabled, and accordingly change the colour of the edit link to white, and change the background colour to orange.
