Can you tell me, as WordPress users, what plugin you are currently missing in the market right now? Something that is genuinely needed, but just doesn't exist. I have a bit of free time and could write a plugin, but I am completely out of the loop regarding the recent state of this CMS.

​I used to develop plugins while working in commercial development. I want to make something for myself, but have it be useful to other users too.

​Could you throw me some ideas?
