Would be helpful if any collection item in your bags/bank were shaded green if you didn't have it collected or red if you did have it collected, versus having to right click and hold down to look at it without eating it to see the same thing. I always thought that, would be nice.
Nice thought but think about this: 1. Every time you open your bags with (how many?) collectibles, every single one goes out and makes a database hit whether you are wanting that data or not. Instead of a single DB hit when you open the description. 2. I know there are other items that are now including some type of info over the icon, but I would assume a translucent color overlay is going to be a big memory hit. We have so many slots available now that opening too many bags overruns the available virtual memory limit and slots stop being drawn. I would be afraid that this would exacerbate that issue.
