Poor Visibility of Copy Files progress bar?
 

Since I can recall, the progress bar on the Copy Files portion of the SuperDuper pane is very hard to see. It appears as darker blue on blue background ( or gray on top of blue) This is not a huge deal, but couldn't it be made more readable on future versions of SuperDuper?

We've tried to attach a "hue" filter to the progress bar to change its color, but that caused exceptions on some systems, especially 10.10/10.11, and we didn't want to drop support for those systems just to change this...

Wow, I agree with Andrew, and am surprised improving visibility could cause problems.

Everything's a surprise when you're dealing with many years' worth of macOS releases.
