Save the binded tools

**Problem description**

When using a lot of different brushs/tools, including "complex" ones like % based spheres with masks and all, you have to redo every single tool every time you load the World.

**Describe the solution you'd like**

It would be very helpful to keep the tools and brushs saved, or allow a way to save the toolbar for next time. Would really made working on big projects easier.

**Describe alternatives you've considered**

I've tried saving every command in a text file and binding them one by one, but it's still a chore and keeping it updated can be annoying.

Thanks for your time.
