I kinda hate the Google Photos UI, UX. Overall it seems very disjointed and it is hard to figure out how to do the things I want to actually do. And then trying to explain it to anybody else is another round of ux hell. It also kills me when I try to upload some photos and then it tells me some failed to upload, and then it doesn't give me any useful way to retry them. No error message that explains why they failed, either. Even though sometimes they do work the 2nd time. W-hate-ver.

Personally, I mostly detest every UI change Firefox ever makes, it would seem. E.g. the latest cylon mode activity animation in the tab thing. Just awful.

It is the year 2017, and as far as I know there is no computer OS that can handle multiple monitors really well, including sometimes just utterly losing video. New macbook pro usb c touchstrip latest mac os x flails in various annoying ways. Relatively recent Ubuntu 16.04 often freaks out wrt multiple monitors, and even goes blank after re-plugging in a video cable. I haven't touched a windows box in a long time, and nothing much newer than Win 7, so I dunno there, but I'd guess there are fubar things about that experience as well.

As far as I can tell, there's no obvious choice for a good photo/image viewer and copier on Linux. gThumb is sorta least bad of all the things I've seen, and it is kind of a complete UX train wreck.
