Add custom filters, extra data rows, more formatting

Hi @noirbizarre,

I've been using this plugin for some time now and I must say that I've come to enjoy it a lot. Granted, I think there are a few things missing, so I decided to contribute to this project by adding them. I haven't managed to add documentation for them yet, but I provide explanations in the commit logs.

Side note: Given that it's been nine months since this repo has been updated, may I ask if it's still maintained?
