Andy Matuschak has an interesting site where he publishes his notes collection as it grows. He does that as an experiment in ‘working with the garage door up’. One thing that makes browsing his note collection pleasant is how he uses sliding panes. When you follow a link to a new note it becomes a pane that slides over the one you are coming from. It means jumping back and forth between notes that form your path through them is easy. A kind of breadcrumb trail but one that keeps the content, not just the page links, available at a glance. This allows you to maintain an overall view while you browse his site.
For Obsidian there’s a plugin that provides sliding panes ‘Andy Matuschak style’ to my notes collection. I’ve installed it to see if it reduces friction that I currently feel if I want to quickly branch out into several notes, while not actually leaving the starting note or having to add panes in a way that easily results in a hard to grasp ‘tree map‘.
