I find the Peek windows handy (the default experience for Find All References and the difference between Go to Definition and Peek Definition).
I find VS Code's Outline tool quite handy. By default it's hidden away at the bottom of the main Explorer tab, but you can turn on the Secondary Sidebar (now with a button at the top of the window) and drag it over on to the Secondary Sidebar to really give it room to grow and not fight your file explorer view for space. (Timeline I also like to move into the Secondary Sidebar as a good place for it.)
Outline resembles the Breadcrumbs at the top of an editor and even if you don't have great bookmarks, being able to quickly expand to a specific symbol in a file is handy.
Also Back/Forward mostly work pretty well in VS Code. If you've got the extra mouse buttons that can be used for Back/Forward in a browser those work well, as does the most common browser shortcut Alt+Left and Alt+Right. In very recent versions you can right click the Title Bar and turn on the Command Center and it gives you Back and Forward buttons there in the title bar, even more like a browser.
(ETA: holding Ctrl+Tab gives you a History menu in the order of Back/Forward sort order.)
> One thing that I haven't played with in VS Code but that bites me a lot (and sorry, I don't know the proper name for this setting/feature) is that often when you're navigating you're doing so in the same vs code tab. If I remember to double-click the tab it'll hang around, but that's a pretty janky workflow, and I don't ALWAYS want to do that.
This is called "Preview". If you don't double click to open the file, you can double-click the tab itself later if you decide to want to keep it open. (There's also Keep Open on the context menus and it has a keyboard shortcut of Ctrl+K Enter.)
You can entirely disable Preview with the Settings key "workbench.editor.enablePreview". (Set it to false. Or uncheck it in the UI.) You could make it apply to only a specific workspace while you are trying to navigate it by adding that to a .vscode/settings.json file in the project (though this specific Setting, I probably would try to avoid checking in to your project repo to avoid annoying other users).
