When I want to add a ruler guide, how can I enter in an x/y value, instead of manually clicking where I want it? In Photoshop you can do so by clicking insert guide, then it gives you a value box, similarly with Illustrator you can type it in once the guide is selected. How about Sketch?
Not elegantly anyway.
A hack I’ve used is to position a rectangle at the coordinates then align the guide to it. It’s lame, but I don’t use guides often.
