"Reader Mode" theme component feedback

It would make more sense if it changed the reading experience in some meaningful way like making it full width in Reader Mode. As it is now, I would probably never use this feature so ironically all it’s doing for me is adding more visual noise to the timeline.

I have some longer term goals to add in options for font, text size, width of content, etc. But for now, this is just a small experiment and a WIP.
