I appreciated how the reddit app I used (relay) kept everything internal. I don’t want all the links I open on this app opening in my browser and plugging up my history. I doubly appreciated how it would open YouTube links in an internal video player that wasn’t linked to my YouTube account in any way. This is a must have for me to prevent my YouTube “algorithm” from getting any ideas. For example, I watch a video about “X” and now my whole feed is suggesting I watch more videos about whatever “X” was.
Agree-ish. It needs the ability to open and display common link types, videos, images, etc.
RiF had an ok system for decisions about what to try and open/display.
For example, I prefer YouTube to open in NewPipe rather than an in app browser, but that might be different for you.
