attached image shows how Tree List Editor (DevExpress, VCL only) allows to configure all nodes.
It would be nice to have some functions available in TMS FNC / Checked Tree View (Configuration), or just allow to open selected in Configuration screen node in object inspector (with double-click, etc.)
your component is very powerful, but it takes more time to setup all nodes comparing to DX.
If you double-click on the TTMSFNCTreeView you will display the editor.
yes, I know about double-click / it allows just rename the node.
in DX I can edit node names and other "key" node properties (assign icons, node type, drag-and-drop) - that allows to build/modify any tree visually using just 1 window.
