No more lives and quick keys for saving and loading

It is very good that now we can save and load but, with this new functionality, it doesn't make much sense anymore to have the ability to have and collect multiple lives and instead it is quite confusing and uncomfortable, so: could you add the option to remove lives (both items and on the HUD)?
To make things even better, i think you also should add quick keys for save, load, quicksave and quickload.
Thanks in advance!
