Perfect balance of intuitive and flexible
The default layouts will get you started right away and illustrate the usefulness of the tool. If you can’t do what you want with the default layouts, the default grid for new layouts is just the right amount of granular to divide up most screens. If it’s not quite granular enough for a large monitor, you can modify the grid to what you like, and if THAT isn’t enough, you can create layouts down to the pixel, but those deeper layers aren’t exposed unless you need them (though they’re not hard to find) so what you end up with is a fully customizable, very powerful organizational tool that never feels overpowered while you’re using it.
