Adding multiple files to qua.

Pick a preset, open a folder, add all to queue.

THX A LOT

This has never worked for me. I have to add files one at a time, which is a right pain...

Sorry, found out how here: https://handbrake.fr/docs/en/1.3.0/advanced/queue.html

I RTFM and followed all instructions and still cannot find where I can multi-select files. If I select a folder, only the top item is loaded, and multi-select of video files doesn't work. I'm on Catalina and the latest version 1.3.1. I see comments above about "add all to queue" - I don't see that option. I accept I must be missing something, can someone tell me if this is possible and what steps to take?
