Feature request: Filtering,and sorting, advance search on openmhz. Display both trunkgroup and description.

Thanks for this project. It works so well and is a wonderful resource.

I'm hosting a 3 RTLSDR server for Utah County in Utah. I would love to be able to search for recordings based on attributes like length and description and trunkgroup and time.

Basically an advanced search where I could specify length over 10 seconds, from these talkgroups, or descriptions.

As a side note it would be nice to display both trunkgroup and description as an option in playback on openMHz.

Thanks!
