Code-Explorer fold and sort for Markdown and others

[ScrKiddle]

In Code-Explorer in the side-panel where it shows the titles and subtitles in an mark-down file it can turn into a vary long list with nested headings

Code: Select all

# Level 1
  ## Level 2.1
  ## Level 2.2
    ### Level 3
# Title1
  ## Subtitle 2.1
  ## Subtitle 2.2
    ### Subsubtitle 3
...

It would be very handy if such nests could get folded in the code-explorer

Code: Select all

[+] # Level 1 (...)
[-] # Title1
[-]  ## Subtitle 2.1
[+]  ## Subtitle 2.2 (...)
...

Even better if titles and theyr sub content could get sorted/reordered in the code-explorer.
