When adding an internal link, you can set it to display alternative text. For example, I’m linking to a README in a sub folder, I can do this:
[[README|More informative title]]
So I link to the README, but when viewing the file or file preview, I see “More informative title”.
However, the graph view continues to show the file name. It would be helpful if it showed the alternative title instead.
I’ve tried to work around it by linking to the title of the README, but again, it just shows the file name in graph view.
