I have discovered that some of the editor "tabs" are not clearly visible. While creating a theme, I completely missed the "Content" tab, as there was no background to the tab, and the text was virtually invisible. The same happens with the "Song tab" on the main display, but that is more apparent as there is the "Song tools" highlight above it.

I'm not sure if this is a general problem in ZW or due to a PC display setting - turning off "transparency" in windows display setting makes the tabs visible. Would it be possible to show an outline to the "non-active" tabs, to make them clearer (like Internet Explorer 11), or decrease the transparency setting?
