In your copious amounts of spare time (ha!) maybe one day you might consider the following:
A "Save All" function, from the file menu or a right-click menu, which would save the current world, current state, and current image with one base name. I keep forgetting what I've named a world by the time I get around to remembering to save the state or a preview image (although this might just be a personal problem I have.)
A "right-click->save world" option for the parameter browser. I am always coming across ones I'd like to explore further at a later time, and would always love to be able to just right-click save something from that window.
Just a couple low-priority requests if you're ever bored.
