PerfectPixel has an option that makes your cursor snap to the loot window.
It helps you to quickly and more easily see the tooltip for whatever you're looking at picking up.
I loved it. I absolutely loved that feature.
It especially came in handy while stealing.
But unfortunately, there were a few things I didn't care for. A few of the UI look changes, and addon conflicts.
So I would love it if someone made a lone addon that offered this feature, or if someone added this feature as an option to one of their addons that have already been developed and released.
One that comes to my mind first would be FCO ChangeStuff. Seems like a nice option to include in that addon.
Additional/Less Important Request: I also really liked how PerfectPixel extended the inventory window to make it longer. I prefer the default UI look, but having the inventory window be longer to see more at once can be a nice QoL change.
