Feature Request: Canvas file as folder note

[batrand]

Hey there! Many thanks for the plugin and keeping it up to date.

I'd love to be able to use a canvas file as the folder note for a folder. That is, just like how in a Folder, a file called Folder.md is treated as the note for that folder, I'm hoping a Folder.canvas file would be treated in a similar manner.

My use case is that I have a folder of media files, and a canvas for layout out those media files. Right now, to get to the canvas, I need to expand the folder and click on the canvas. I'd like to be able to just click on the folder and see the canvas instead.

The next release will include this change took me way longer than expected though
