+sparse tree based on the category of the notes
+@item Create your your own highlighter pens with different colors, type (e.g.
+underline, squiggle, etc. optionally with Org’s category for search and filter
+on your highlights and notes)
+@item Have the same highlighting and annotating functionality for websites
