I use the "idle" theme, straight black on white. I like the new tabs on the top. Easier to see which file is current. Thanks! Now, the scroll bar knob color is too dark on my screen. Often I can't see where the knob is. On this very wide LCD screen, there isn't enough contrast between the scroll-bar "gutter" and the knob. What can I do to change the color of this? Is there am image I can edit, or a parameter setting in a file somewhere?
