I don't know if those are the three most recent because I have no idea how to look that up but they're quite recent: MAPfrappe allows you to compare the outlines of different countries/cities/regions by projecting them onto Google Maps. You can even create your own outlines. Very useful to get a feeling of how a big certain region really is. Resemble.js basically like diff but for images. Lets you compare two images. Geacron an interactive map of how the world looked (politically) in a given year. Really useful!
Chrome. And yes, they do settle at the bottom of the folder but I have different folders and just recently moved some bookmarks, so it's kind of hard for me to know which ones were the most recent. Hah, thank you! :) I'm actually more into history but those two kind of go hand in hand.Which browser do you use? I think the latest bookmarks usually settle at the bottom. But any three would do.
Looks like you are very much into geography! Super interesting!
