Increase the contrast of the new slide pluses and grid lines
The contrast of the new page 'plus' button is so low that I could not see them at all on one of my monitors. On the other I can only see the horizontal one. The grid lines are also extremely hard to see.
I had to go to the help to figure out how to create a new vertical slide.
The problem is of course monitor and viewing angle dependent. But I haven't done anything particular about this (work) setup, so perhaps more people have problems. It is a pretty bad first experience to not be able to add a new slide.
I took some pictures, but don't know how to upload them. I can also make a movie of me changing the monitor contrast slowly. At about 50% the grid lines suddenly appear/disappear.
