With KeeTheme 0.9.0 and using a KeeTheme.ini, a selected node in an inactive treeview is barely visible as the font color and background of the selection are almost the same shade of light grey. I found no equivlane tini parameter to define a color for inactive SelectionColor and SelectionBackColor.
Without a KeeTheme.ini (default KeeTheme Dark mode) the selected node retains the light grey font color and blueish background color, just losing the dotted frame around the active node. So it is still well readable.
