I really love the ease of the Save State feature. I'm happily using it to progress further* in games.
Please could we have a "Load State" button in the F12 menu? At the moment I have to Quit (and Confirm Quit) back to the game launcher, wait a few seconds for the buttons to unshade, and then launch the game again. Might not sound like much, but if you have to tackle a particularly tricky bit then it all adds up.
