I really like the "mark page read" feature, so I'll float another request to you.
When I'm looking at pages of unread posts, sometimes the size of the text is large and easy to read and sometimes the size of the text is small and much harder to read. Your board probably uses the length of the longest thread title in the size algorithm. My ask is that you bump up the size to make it easy for me of a certain age to read on a phone. I'll attach screenshots of Page 1 and Page 2 of unread messages showing the larger and smaller text to give you an idea.
I would just resize the page, but when I do that it doesn't all fit on the screen and wrap the lines.
