If you have chosen to install NewIcons in ClassicWB then TL can recognize NewIcon's ToolTypes.
ToolTypes Support is new on TinyLancher, it seems that it can detect TT on STD Icons but if you want to detect TT on NewIcons you have to use NewIcons (The App). I will add an option to disable TT recognition.
Maybe Bloodwych will add TinyLauncher on ClassicWB once it's stable, so you won't have to worry about configuration
