My antiquated eyeballs have lots of trouble finding the mouse cursor, especially when it turns itself into a very thin line, as it often does in Pan and in gnome-terminal.
The eyeballs on the panels help some, especially if I manage to center them. But CentOS 6 has a better way. If I choose the oxygen theme, I can get a big fat yellow arrow. (It also turns into a line sometimes, but even then, it's much bigger, and still yellow.
Would somebody who knows how please make this available in Fedora, or write a pons asinorum for it? When you get seriously old, you'll be glad you did.
