Filtering, ordering and pagination via Flop

Most of us have created our own filtering, sorting and pagination code before in one project after the other. Mathias Polligkeit got tired of doing that too and created the flop library to wrap it all into a portable and reusable solution. We talk with Mathias to learn what it can do and are pleased to learn it's surpassed our own solutions. He also created a flop_phoenix package with heex components to help build filter forms and tables. A fun look into an interesting library!
