Why there are few questions which has yellow background instead of normal white in EE stackexchange. Is there any priority or something? Is this something related to the new design? What does this mean?
It happens when a question contains one of your favorite tags, so you must have one of microcontroller, audio or embedded selected under your favorite tags. I'm pretty sure it has been a feature quite a while (although I don't use it myself) so maybe the color scheme has just changed under the new layout which makes it more apparent. But I guess more likely you've probably just added some favorite tags?
