You could teach nose and paw targeting, once you have that down you can use it to do all sorts like closing draws and doors, turning lights on and off (if she's tall enough!), pushing a ball along.
My favourite thing I've ever taught my dog is 'pick it up' he will fetch me pretty much anything (within reason) that I point at and ask for, start off with teaching her to pick up a favourite toy and then make the items more difficult, like different shapes, textures and weights. It took him ages to learn to pick a book up tidy but it's worth it because people are always charmed when they see him fetch me something, it's also dead useful.
There is probably loads of vids on you tube on retrieving or holding objects which is all 'pick it up' is.
I like the sword fighting vid of kikopups, you could start the foundations of that inside.
