is there any plan to allow for some organization on the sidebar for dendron published sites? i know that a lot of documentation sites, for example gitbook, allow for organizing the sidebar in a way that feels like it's really manageable / easy to find what you need. i'm wondering if there is a similar solution for dendron. i think one 80/20 might be just allowing the sidebar to be default expanded so for example in the image i posted, each of those sections with subsections would be like a root level note, and you can specify a depth (default of 1) to view whats under it. just curious on everyones thoughts here
