Browsing through the items, I looked at the Potion of Healing (Supreme) page. I'm on a Galaxy S7 and was in Portrait mode. Both the list view and individual page view had the titles cut off for numerous items because they were too long. Landscape view helped most of them, but some were still a bit too long to fully display the title. Is there functionality to expand page titles on mobile?

I have the same issue on iPhone 6S. I can see the whole name of some items only viewing its specific page in landscape mode (it's not enough to put the list in landscape mode). This is a bit inconvenient with items that have multiple slightly different entries in the list (e.g. Potions of giant strength)

On my iPhone 6+ the top of the navigational menu is cut-off which makes it very difficult to use the site.

Additionally, when in mobile, if you click the option in the man for the desktop version while using your mobile device, the resulting page has a lot of issues.

The navigation background does not expand enough, so have of the white text is on white background.

You cannot really get back to prior view format. Still trying to figure out where/how.
