Thanks for starting the discussion on this and for the shout out. At first I've created slidestr.net as a tool to see my own photography profile when there were no galleries in nostrudel, snort, etc. yet.

I like the masonry type view and have implemented it multiple times since 2016, when I stole it from Google Photos the first time. That being said, it makes most sense on desktop with more horizontal space.

I'll take some ideas from this right away to implement in slidestr and make it less clunky to use. There are some things that can be easily done but other, i.e. reverse lookup of group memberships would require some backend magic, where someone needs to write a smart DVM 😄 

I'm in Madeira from the 26th if you want to take the time to discuss ideas IRL #soveng
