I use the 500px extension and I love this app for its dimming slider. Don't use the blur. However, it would be great if it were more like Gainos, which caches the last 10 wallpapers so you can go back to ones you may have missed or would like to keep around for a while longer. Gainos is also not a live wallpaper, but rather an app which simply retrieves and applies the wallpaper. I'm torn between the two, but the dimming is really great for white transparent text on your homescreen.
XDA needs a "2nd Post Wiki" automatically generated in each thread. Such a thread wiki has proven effective on other sites to cut down on useless thread clutter and questions which have been answered repeatedly. The idea is simple. A community-editable wiki is inserted immediately beneath the OP to address current issues relating to the topic. Most OP/devs don't have the time to continually update their OP to address ongoing issues. Let's let the community do that for them!
