P: Line grid while cropping that is easy to see

Many many times I’ve struggled with seeing the lines in the grid that appears while cropping and rotating. The lines are too transparent and do not stand out against a lot of photos.

Can you make them a stronger color? Or an inverted color or something? They don’t need to be thicker, they just need to be easy to see. 
 

And can you add an option to have them visible all the time, not only when you’re actively cropping or rotating?

(The screenshot isn’t there to show how hard they’re to see. It’s there to show what lines I’m talking about. I’m talking about the lines in the grid when cropping.)
