  * @file lllineeditor.h
  * @brief Text editor widget to let users enter/edit a single line.
  *
- * Features: 
- *		Text entry of a single line (text, delete, left and right arrow, insert, return).
- *		Callbacks either on every keystroke or just on the return key.
- *		Focus (allow multiple text entry widgets)
- *		Clipboard (cut, copy, and paste)
- *		Horizontal scrolling to allow strings longer than widget size allows 
- *		Pre-validation (limit which keys can be used)
- *		Optional line history so previous entries can be recalled by CTRL UP/DOWN
