Formatting

The following options are available for formatting branches:

Flip the tree horizontally ﬂips the tree so that branches go from right to left, rather than left to right.
Transform branches allows the branches to be equal like a cladogram, or proportional. Leaving it unselected leaves the tree in its original form.
Ordering orders branches in increasing or decreasing order of length, but within each clade or cluster.
Show root branch displays the position of the root of the tree (has no eﬀect in the unrooted layout).
Line weight can be increased or decreased to change the thickness of the lines representing the branches.
Show selected subtree only shows only the part of the tree that is selected (or the entire tree if there is no selection).
