I am finding it hard to differentiate between the light & dark blue quote bubbles in the "who quoted me" widget (or at least, it is not immediately obvious). It would be nice if the colour could be adjusted so as to create a greater contrast between old & new quotes, because at the moment I feel like I have to double-check to see whether I've been quoted recently.
I also think it would make more sense to have unread quotes in a brighter colour than read ones, rather than the other way around. Brightness is more suggestive of new and hence it is more appropriate, in my opinion.
