Sorry for this late reply, imo Toolbar Editor is more simple and intuitive than LOTT, It can be a bit cumbersome when you drag the tool you want to the toolbar you´re creating but it´s nothing hard to understand how it works, and the main reason I prefer it is because the toolbars can be docked on windows just like any othe toolbar, LOTT lets you with floating toolbars, I dont know if something has changed since the last time I used it but it was impossible to dock toolbars made with Fredo´s extension.
Here´s the file Dan created and the steps to make Toolbar editor work on sketchup 2024 and 2025
