Illustrator has done it right.
- dragging guides out of the rulers is easy
- guides snap and show relations via smart guides
- guides can be selected and moves via the keyboard & the position value can be easily adjusted in pixels
- smart guides help when positioning and resizing layers
- snapping helps to change the origin for the ruler
- elements snap to guides
Its also an Abobe tool, so please copy this behaviour over. In comparison illustrator feels like a very old, outdated software, even though you obviously know how to do it right.
Cheers
