Themeroller and Icon Filename Case

I just recently updated my theme on themeroller, only to discover that most icons had vanished, with the exception of hover icons.

Upon inspection of the CSS, I realized that themeroller had converted the hex color code to lowercase in the icon filename, but not in the CSS file itself; it copied verbatim what was in text boxes. Apparently I had typed the color code in lowercase for the hover icons, but in uppercase for the rest. Oddly enough, it displayed correctly on the test page, only adding to the confusion.

A simple fix would be to apply a case-consistency rule across the board. Stick with either uppercase or lowercase and force it on all color codes wherever they're used.

I rated this as a fairly major bug, as themeroller is supposed to make CSS easy for those who aren't familiar with it. Many beginning users that experience an issue like this will just reach the conclusion that it doesn't work and move to something else.
