The red disk will let you position your paper without exposing it.
I'm here with all the rest. I'm also over 30 years of programming/sysadmin/etc, I don't compile my own operating systems or make cross-compilers anymore but still spend many hours at my keyboard and still more than 40/week. Most of my hobbies don't involve computers ( some have parts that do.. I also am into amateur radio astronomy which needs custom software )
That's part of the draw to film for me, but I also like the "tangible' and physical aspect of it, as well as the manual craft part. I just got back to film after being away >30 years.
As for the red disc, I'm pretty sure that the idea is that you can put your paper on the easel, focus the enlarger (with the red light), remove the red disc, and then expose your print. Supposedly the red light won't fog paper. My enlarger has a similar device, but I don't use it and instead focus on a separate piece of white paper before taking out the photo paper and making my print. I find this much simpler, plus I don't have to worry about any possible fogging. I don't know about the rectangles, perhaps they correspond to paper sizes?
Welcome Home Zack !
Not long ago I replaced them with Ansel Adam's Triology, BTZS - Phil Davis and few others. Much more relaxing now...

This is not the carrier from durst. The 6x6 is from durst and from what I understand, the 6x6 had a plate you added for 35mm film. My 35mm carrier is 5/8 too wide and a bit too long and no brand shown.
Thank you all for the warm welcome! I'm very excited to be part of this group and learn more about this fine art we call photography and darkroom magic. :)
I may be wrong but I would guess these allow you to see the sprocketed part of the film where the info about film type and exposure number are.
