"MagicLayout". a quick & dirty method for fine adjustment of numeric values in swiftUI, such as padding. I found it easier than previews. It doesn't do anything more than what previews claim to do 😄 : IE, change values on the fly and see the results.

for MacOS/SwiftUI

Usage:
initialize:

       var magicLayoutWindow = MagicLayoutWindow()

layout: use a magic variable (eg, magic.m1) for the value you want to set, and it will be wired up to the controls in the floating window. pass it a starting guess

	Button("Reset"){}
	.padding(.trailing,magic.m1(20)) // show live controls for trailing padding, starting with 20px.  
	
	Text("I don't know what font size to use")
	.font(.system(size: magic.m2(16))) // make font size adjustable

You can also use a magic var as a color.

This relies on my public package, "SingleWindow" which creates the floating window, and adds a menu item to open it. magiclayout isn't set up as a package yet. just grab the source file. SingleWindow is a swift package.

probably not thread safe.
