Filtering feature

A quick log for shit and giggles: technical debt diff from the new filtering feature.

+x / -y are the number of lines of code added/removed. For a given feature, best practices are to have the lowest number of code lines at the end because each line is a chance of bug and long code is hard to maintain, debug and extend. See overengineering
