André, I have mentioned in the past that I really like your new color inset. (Attached is the lyx file I used to generate the 'improved' buttons in the Qt math toolbar.)
However, it is very intrusive isn't it? Instead of displaying a fraction as [blue]a ------- [blue]b wouldn't it be more elegant to use the math-macro display machinery? Ie, the display only gets expanded to '[blue]a' when the cursor enters the inset. Thoughts? Angus ps apologies if my replies take a long time to come through. gmane appears to be suffering from a nasty slow up so it takes ages for the posts to become visible.
