Compact search filters

This PR is an effort to free up as much real estate as possible in the record filter area to better accommodate smaller screen sizes (such as 13" laptops) and also to make the general UX less overwhelming.

If you have a smaller-sized screen, please test this branch and leave your feedback with a screenshot!
