Please enable use of ArcGIS Pro that doesn't require the creation of a whole project folder and file structure. Please allow the USER to decide if they want to save.
MUCH of the time when I use ArcMap I don't intend to save my work. I often open a new ArcMap window to view data, to test layer symbology for combinations of layers for a map that I'm working on in another window, or to test in a clean environment when I'm having a problem in another map. I also do it for many other reasons too numerous to mention. In these cases I either know or suspect that I won't need to save the map, and plan to save only if I need to. It's a no-brainer.
So...WHY...when starting up ArcGIS Pro, does ESRI insist that we have to create a whole, messy, space-consuming project folder, complete with File Geodatabase that we may have NO INTENTION of using, before allowing us even to view any data? Unknown.
