Suppress extra space between root nodes in the Shelltree

Question / Problem

The TJamShellTree seems to add extra space between root nodes. Is this controllable by some setting?

Answer / Solution

Indeed, by default additional space is added between root nodes. While it is unfortunately technically not possible to reduce the extra space, you can remove it, using the "SingleSpacedRoots" property. If set to true, all extra space is removed.
