Very nice article!

But I found two little errors or lazinesses:

• In the section "text-folding" you wrote
  

  " Folding configuration
  set foldmethod=marker
  " Edit and uncomment next line if you want non-default marker
  "set foldmarker="[[[,]]]"
  [download]

  
  I guess you deleted the wrong line and meant
  set foldmarker="{{{,}}}"
  instead of the last line?!

• You used the comment
  " This is for winmanager
  more then once, even in the section "Tag explorer".
