I use toolbar editor and I’m not facing any issues with it, I just replaced the file that Dan created on the plugins folder and it works perfectly on windows and macOS.
I prefer toolbar editor over LOTT, probably I have an OCT but I can’t stand the toolbar on top of of the screen that can’t be docked or hidden. The toolbars from LOTT can’t be docked on windows like the ones created with toolbar editor, on Mac you can’t dock toolbars(yet) but the toolbars look like the native ones also by some reason, I couldn’t create a toolbar for V-Ray with LOTT, I tried every setting, on the toolbar manager there’s even an option to allow or not to create a V-Ray toolbar, I restarted SketchUp uninstalled and re installed the plugin, and it was impossible for me to create it, maybe it’s fixed now but anyways Toolbar editor is a lot easier to use imho.
