  MISSION STATEMENT
  =================
 
  - easy to use to create code-driven and data-driven tools
- - easy to use to create adhoc short-lived tools and long-lived, more elaborate tools
+ - easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools
  - easy to hack and improve
  - minimize screen real-estate usage
  - minimize setup and maintainance
  - minimize state storage on user side
  - portable, minimize dependencies, run on target (consoles, etc.)
- - efficient runtime (nb- we do allocate when "growing" content - creating a window / opening a tree node for the first time, etc. - but a typical frame won't allocate anything)
