Here's a file I'm currently trying to bring up to production level:
The main portal has 12 records visible but, as you can see if you look closely, there are more related records that you might be able to bring into view if you scroll. But the near-total absence of contrast between the white thumb and the ultra-light gray background on the scroll bar makes it very easy for the users to overlook the availability of additional related records.
However, despite a frustrating hour with the Appearance Inspector, I can't figure out how to change the color scheme to provide better contrast. Any ideas? (It's Enlightened theme, if that helps.)
