Straighten tool too small to see

[VP_photo_club_prez]

Is there a way to enlarge or make bold the straighten tool? It gets lost in some of the images. Sadly my eyesight isn't what it used to be.

I don't know of a way the enlarge the tool but what I do is zoom into the image by pressing "Ctrl +". It doesn't make to tool bigger but I find it easier to see. "Ctrl 0" to make image to normal size.

Buy a 32" monitor- it makes everything big.
