I love the DOI->PDF single search, it's how it should be. I'd prefer a better more responsive format, (PDFs are still hard to read on a phone or less than huge tablet) but nothing is quite as good for, "just give me the damn paper".
And editorship is highly variable, even at the highest end. I remember catching an article in Nature where two curves in separate panes were clearly copy-pasted yet claimed to be different conditions in the legend.
Fully agree here; whether PDF is best is really debatable, but I want the 'one click to get a useful format' rather than having to struggle with their badly-implemented readers (which, by the way, are lacking accessibility; I am your quintessential near-sighted nerd and I often have to 'manually zoom' because some dolt thought it might be a good idea to deactivate increasing the font size).
