Guides?

Does anyone know if it is possible to create Photoshop-Style guides in Unity for use with the UI system, I don’t want to use 1 pixel panels as they take up a lot of room in the hierarchy, just wondering if there were any scripts or other ways to achieve this, I am looking for custom colors as well (not a requirement, I’m just used to it).

Horizontal: RGB(0, 255, 0)
Vertical: RGB(200, 0, 200)

Anything at all?

You can do vertex snapping in the scene view by holding down the v key while moving a transform, but I haven’t tried this with the new UI. I’m sure this wouldn’t work just like PS, but it might help in some situations. Non snapping lines could be achieved with Editor code. Snapping of course would require more editor code, but it is possible.
