That was very likely Street Complete which is self explanatory and a great way to start. You are adding all kinds of useful information about any kind of object or building with this.

There’s also Vespucci which allows to alter the whole map (ie edit streets, POIs and so on) but takes a lot more to get familiar with.

I use the addon Sideberry (for vertical tabs) and it brings the option to unload specific tabs with it’s context menu.

I don’t get why about:unloads doesn’t let the user decide which specific tabs they want to close.

Awesome thanks for the all this info!

A memory jog, that describes it neatly thanks for the new word. Also nice touch with the shoes :D

Same here. If there’s a Handy tutorial anyone would suggest to get familiar with those abilities I’d love to hear about them.

I sometimes had a very small piece of paper scribbled with stuff I couldn’t remember while learning but turns out this way I knew what I had written down there and didn’t need it afterall :D

One time I accidentally forgot about that tiny paper though and my teacher actually found it on some stairs and recognized my handwriting.

No need, there’s enough other better suited places where news like this can be discussed.
