There aren't enough digital french cleat systems.
The true benefit of a French cleat isn't storage or organizing the way a fiddly pegboard and hanger approach uses, it's the ability to move all tools for a specific project onto a single rail without having to fiddle around, reducing friction for engaging and re-engaging with a project.
Just out of curiosity, what is a French cleat? I've only found references to building (real) shelves on Google.
