So, first I'd like to make clear that none of the underlying collections or data has moved anywhere. That is, all the items that are in a collection of, say, newspapers or music performances are still there - the URLs are precisely the same and were designed to be permanent. Nobody's shifting those around here. Google searches work, and the site search works the same, using the same criteria.
Next, in the results pages, which include those "tiles" and infinite scrolling that is not to you taste, if you look in the upper right (next to the "Results" number), there's an icon that changes from tile mode to "list" mode. You can also turn on "details". That makes things into a list form, at least. However, for the moment, infinite scroll will still be engaged. Also note you can sort the list alphabetically, by creator, or by views.
After doing those two steps, is the problem at that point JUST the infinite scroll? Is that what makes it a mess for you? Or is it a different set of issues? I'm happy to hear it in this thread, but also, if you click the "beta" button in the upper right, and write exactly what you'd like, I guarantee it's read.
