Loving the power and simplicity of the plugin... Amazing work,!

I'm currently working on a Fate Core implementation in RMMV and very much seeing this as the heart of my skills systems.

Just wondering if there's scope within my meager javascript knowledge to adapt this to a skills pyramid; essentially capping the max you can apply to any one skill based on the values of the others.

So essentially every skill would be 0 and you can level up according to a scale, starting with 20 points that can apply in the order of-

1x 4 point skill   [ ]
2x 3 point skill   [ ] [ ]
3x 2 point skill   [ ] [ ] [ ]
4x 1 point skill   [ ] [ ] [ ] [ ]

You'd only be able to level up a skill if there a supporting level beneath it, so your next upgrade would be either a 5th 1 point skill, a 4th 2 point skill, a third 3 point skill, or a 2nd 5 point skill, provided you had adequate points.

Has anyone else looked at doing something along these lines?
