Description

Similar to what is done in Line Highlight where the given few lines are highlighted, in this case, the given few lines would be shown while the other ones would be hidden. The hidden lines could be made visible with a click of an icon representing 'expand'. This is similar functionality to that of a code editor, or what GitHub has in diffs.

Research direction

Start by reading the existing Line Highlight implementation and compare the requested behavior with code-editor and GitHub diff collapsing. Define how the selected lines, expand control, and hidden lines should behave, then verify that the requested lines are shown by default and the others can be revealed with the control.
