It's possible to change order of element blocks in the Table of Contents with the mouse by dragging and dropping, but is it possible to do sorting? For example on a TOC like
# 1
## c
## a
## b
# 3
## b
## c
## a
# 2
## a
## c
## b
how can I sort alphabetically only H1 headers by name? Or only the H2 headers? Or reverse sort?
