I too really like the consistent bridging object idea. Although often some events are part of multiple categories, and which object will you use then?
I’m a huge fan of enriching loci. I’m always concerned that there is no reality backing up the details I’m adding (so I just have to remember them unless I write them down, which I never will), but I always end up remembering them
A little story that connects each item would be stickier than a linked list
