Branch markers

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.

A red arrow points at the square button in the middle of and bottom of the branch marker labeled v4.0.bl4_main.

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.
