I just used D&D Beyond in a normal case at games night where I had to look up a spell. I didn't search for it since I already had my Wizard Spells filtered to Cantrips and 1st Level and I realised that the spells were broken down into pages.

The time it took me to scan the first page quickly, click next page, wait for it to load, find the spell, click the spell and then wait the second for it to open. This took longer than the guy across from me who bent over, picked up his PHB, opened it up, found the spell flipping through pages, and read it out to the group...

Please tell me pages are something you'll get rid of. They are a waste of time and absolutely have a negative impact on the usefulness of D&D Beyond. An infinite scrolling list seems to be far better suited to the function of what this is supposed to offer. Especially on a mobile phone.

Better idea: so as to not annoy the inevitable people who like the current system, add the ability to change the number of items on each page of the list (up to and including "all"). 

That works too, but I sure as hell don't want to have to do that every time I get a list of stuff. Other sites are fully capable of loading the next set of items when you get to the bottom of the page, I don't understand why that wasn't done here.
