Great tool, but lose it on dark pages Rated 4 out of 5 stars

I love the MeasureIt tool, and use it frequently. I have two issues that I'd love to see fixed (or explained what I'm doing wrong):

One is that I lose the crosshairs on web pages with a dark background. I'd love for the tool to automatically turn white or yellow or red or some easily see-able color on dark pages.

The other is that I find that the boxes are not re-sizable. I thought they used to be. Can that be fixed?

And a feature request: It would be great to be able to specify an exact size so that I don't have to struggle to drag a box of a certain size. Additionally, it would also be useful to be able to specify one dimension, but let the other be changeable when the box is drawn.


This review is for a previous version of the add-on ( 

That's a great suggestion. Thanks jandreasen!
