Custom Properties panel should have more options

I was going through different rigging options, and for one stumbled upon rigify which does a lot of the workload for you. But a thing i noticed it achieves through scripting is custom buttons

You can achieve something similar with the Custom Properties panel on every object. But the only option you have through the UI is making a slider going from one number to another. And they're also specific to the one selected bone, if it's in pose mode, ideally you'd want any custom properties visible at all times when animating a specific rig.

I’d propose making options for having toggle-able buttons, sliders and perhaps more through the Custom properties panels. And add them to different categories, that would then be displayed in the N-menu for the selected object. would just create the slider/button, and then you can link it up with drivers manually like you would normal custom properties.

Here's a crude mockup of what it could maybe look like, i reckon there's a better alternative to what i called "alignment" though.

I'm attempting to learn python now just to make rigging and animating easier, but i think it should be easy out of the box personally :D The application for it could stretch to every other part of animation too though, like animating properties of materials, or modifiers
