On my Sony z3 compact tablet, they've added 'Small apps' which are small floating widgets you can push about the screen such as a calculator or postit. Essentially they're the same idea as Desktop Accessories from the first Mac. They're surprisingly handy.

I'd love to see that kind of thing come to Sailfish. Full desktop style windows... No. If anyone has used an early Mac with a 9" screen you'll realise why everyone used to install Windowshade, run everything fullscreen and make extensive use of task switchers and the app menu. For similar reasons and more I think tablets are best used full screen.
