Represents a linear sequence of versions. Every element has at least a main branch, but some elements may have several subbranches to isolate work on such tasks as bug fixing, code reorganization, experimentation, and platform-specific development.
The button at the bottom of the branch marker allows you to collapse or expand the display of the versions and branches on that branch.
- If the button in a particular branch marker contains a plus sign (+), there are hidden versions and/or subbranches on that branch. Clicking the button expands the version tree display to show these versions and subbranches.
- If the button contains a minus sign (-), clicking it collapses the branch in the display, hiding the versions and/or subbranches on that branch.
