Vertical Split of Sidebar - Way to save layout?

I’ve been searching for a package or method to save the layout/workspace that includes the tree-view or sidebar within that scope. Basically the right sidebar where the tabs for GitHub and Git are (I assume by default), I split down. This is so I can see document map or Outline while also seeing, lets say, To-Do Show tab below it. My document panes always remain intact, but sidebars always reset.

redactions = I use a lot of profanity within my naming conventions…
