I clicked on All Collections, searched for an icon and found a few, but then I wanted to view other icons in it's collection. I don't see a way to do that, or even figure out that icon's source. Also, the "Search Icons" box is cleared when I move between collections. No (obvious?) way to sort the collections by the number of icons.
I’ve got to ask, which other Wi-Fi mapping provider requires a SSID suffix to opt out? Is it one of the big boys or is it someone like wigle.net or openwifimap.net?
Have you heard of Wik? https://wik.netlify.app/#Home
I just discovered it a couple of months ago and have been using it every day since. It stores everything in your web browser’s LocalStorage. The downside is that every web browser you use has independent data. This also means that backing up your data is entirely on you. However, it is fairly simple to download the entire database and back it up some place. I keep meaning to write a script to merge different instances, but haven’t gotten around to it yet.
Do you know about curl/wget? Each one does pretty much the same thing as the other, but you can start a religious war by suggesting that one is preferable.
Anyway, either of them will let you mirror a website so you never have to worry about it going down.
And, since every Unix command line tool inevitably gets mined and turned into a web service, you could always submit those urls to archive.org instead of or as well as curl-ing/wget-ing them.
