OK. I was on iPad before. Now Mac.
I know this is a big ask, but will you consider not using the "frames" interface. I know it's not old-school HTML frames. But, the header and footer combine to take up around 1/5 (20%) of the screen real estate, depending on the monitor being used. Maybe shrink it down to the nav bar only?
EDIT: It seems that the header is locked on Firefox but it auto expands on Safari. It could just be me. I have a lot of script blockers and plugins on my firefox. I allow most of what BF has going on. But, maybe one that I block is responsible for the auto-hide header. Hmmm....
Also, please don't bring back that old "Mobile Friendly" version of the site
I would immediately request the desktop version every time when using my iPhone. This spoofs the UserAgent and tells the server that my phone is a desktop browser an thus serves up the non-mobile-friendly normal site, which worked just fine.
Keep up the good work.
