Micro Task Management Language (MTML)

• Generalized task management notation.

• Symbols:

  Symbol	Meaning
  !	Important.
  +	Task.
  -	Metadata / elaboration on previous line.
  ~	Thought / idea.
  ~~	Thought / idea in flow.
  ~~~	Thought / idea in multi-day flow.
  %	Edge / trading idea.
  ?	Question.
  @	Topic, can be nested (useful in the calendar).
  $	Performance related task / idea.
  ^	Test.
  &	Refactoring.
  #	Bug.
  <>	Think about it / sleep on it, a coda in blocks.
  .	Relevant to this particular day (usually in the calendar).

• Blocks:

  • Symbols can be combined with other symbols.
  • Small topic is either one line or condensed multiple lines.
  • Big topic is surrounded by @ symbols and contains small topics.
  • Code blocks / comments appear verbatim without any symbols.
  • When in flow, elaboration hyphens can be omitted.

• Examples:

  !+ this is an important task
  - with some metadata here
  
  $& this is a performance related refactoring
  
  @ this is a big topic
  ~ with some ideas
  
  @ sub topic
  ~ with some ideas (related to the super topic)
  
  + tasks
  
  # bugs
  
  ? questions
  
  .^ and some tests to be performed today 
  @ this is a big topic (same text as in the first symbol)
