One thing I do pretty frequently is to try out rigs from various locations - Rig Exchange, folders I've created for purchased rigs, Rig packs, etc. If I load a rig and like it I then use the Store Rig in Local Library or I store it to the Kemper. Problem is that after doing this the window is now set to where I've stored the copy to. If I want to get back to what I was looking through I need to remember where I was and re-navigate to where I left off so I can keep trying other rigs I had found. Even more of a pain if I had sorted or filtered things in some way.
I know I can open two windows and drag and drop between them, but if there was a way to just leave the focus on where I was when I saved instead of moving to where I saved to, or maybe just a way to return to where I was before the Save it would be a lot more natural. I use multiple windows sometimes for things like building a performance, but I'd prefer to stick with one for something this simple.
Most programs keep a Most Recently Used set somewhere in the program menus so you can easily return to something you were looking at earlier.
