The Pane Relief plugin implements this; you can find it in the âCommunity Pluginsâ section of your Obsidian settings (click âBrowseâ, then search for Pane Relief).
The plugin provides you with per-pane history, makes the back and forward buttons in the title bar display what file(s) they go to, and you can right-click them to display a list of forward and back destinations (which you can then right-click to do things to, drag links from, or ctrl/cmd-click to open in a new pane with an identical history trail).
Each pane will have its own history, separate from the others. The history is also saved with the workspace, in a way compatible with both the built-in Workspaces plugin and the community Workspaces Plus plugin.
