Maybe it is just me grappling with this, but I find it extremely hard to see the overset text ‘+’ in the bottom right of the text frames. Sure, I can go to preflight panel and resolve everything from there, but I often fix many other things too as I go and work quite visually. If the box had a red fill and the + was white, it would stand out better. Currently I have to zoom way out to get an idea of where they are.
