When HedgeDoc 2.0 comes out, it will have an “Explore Page” which is the last missing piece to pretty much have feature parity with keep. That said, it’s a long way out.

lol I do love this video

ffmpeg can make you breakfast if you try hard enough lol. It’s so versatile

With ffmpeg in windows, you can listen to a UDP stream using the ffplay command. you can set up a udp stream as an output in ffmpeg in Linux. I would set up a virtual sink that goes nowhere in pulseaudio or pipewire to set as your output device and have ffmpeg listen to that sink. There are lots of options in ffmpeg available to tweak latency and quality.

if the improv is the part that you really enjoy, anything on Dropout is worth checking out.
