@Jeber I am a compulsive daily cookie-wiper so Ostrich mode never persists for me and it is (sorry) a pain to re-enable it every time I log in. It does help, tho. Thank you for mentioning it again.
Basically, I want a one-column stream that is easy on the eyes...

@EileenKCarpenter Got it now, thanks again. Step by step, inch by inch...

@tyghebright You are a lifesaver, I did not know about Ostrich mode. Helps a lot, thanks thanks thanks.

@kel My screen resolution is 1366x768, is that considered suboptimal nowadays? What is yours if you don't mind sharing...

@tyghebright I did get a slider to finally appear after I resized the window itself per @misslovelymess instructions - TY

@misslovelymess @kel
Here is proof that the right "info" column disappers (on my pc) after zooming out...
Thank you for suggestions, people are very nice on this site!

@EileenKCarpenter I haven't followed anyone yet, to my knowledge. Am I accidentally doing that by hitting the Star (which I assumed is equivalent to a Like) - ? Oh lordy, I better log out and spend some time reading the PDF guide.

@ExitiumMachina It's a mystery - for now. Thanks.

@fuzzywunkle Thanks!! I screenshotted your post. At least I now know what the heck it says.

@kel TY but right hand column still vanishes when I do that - replaced by blank gray space.

@Maryleeferris and probably some that I can't see yet -
Thank You all for your encouragement! It will take me a while to figure this all out. Is there a character limit here?
