Clicking on the content of a split will focus that split. While focused, the<a class="reference-link" href="Note%20Tree.md">Note Tree</a>will also indicate the note that is being edited.
When a new split is created, it will share the same note hoisting as the previous one. An easy solution to this is to simply hoist the notes after the split is created.
This is generally quite useful for reorganizing notes from one place to the other, by hoisting the old place in the first split and hoisting the new place to the second one. This will allow easy cut and paste without the tree jumping around from switching between notes.
