and (2) nomenclatur= e such as branches and leaves challenge the formal nomenclature of evolutionary trees. There are also problems with the use of leaves and branches. Formally, "l= eaves" are end-nodes with no children; whereas "branches" are the lines connecting th= e nodes, their lengths commonly interpreted as time estimates. Thusly, "branches" effect= ively describe the "body", not nodes themselves. I advise and lay out a system based on a formal Phylogenetic Tree that imp= lement Show-Hide Options. Show All (currently: Show All [unchanged]) Show Offsprings (currently: Show Children) Show Descendants (currently: Show Branches) Show Sub-Tree (currently: Show Subtree [unchanged]) Show Common Level (currently: Hide Sublevels) Hide Sub-Branches (currently: Hide Leaves - meaning Hide Body after headin= g) Hide Branches (currently: Hide Body, leaves all headings visible) Hide Current Branch (currently: Hide Entry - hide body of this heading) Hide Sub-Tree (currently: Hide Subtree [unchanged]) Hide Other (currently: Hide Other [unchanged]) Regards Peter
