Use case or problem
Some of my notes are really long, especially the ones which I use as a Vault Changelog. In the case of such notes, I use the outline view to navigate across the H2 headings which are Changelog Update Dates.
However, I have to click the outline to go to a particular date, to read its contents. I really wish there was a means to glance at the overview without having to scroll or click
Proposed solution
Implementing a Hover Preview which extends also to the Core Outline plugin would be an ideal solution to the problem.
