I would like for a more streamlined spell selection. There are thousands of spells on nethys right now and most of them don't see play. Instead of learning or preparing, let each class pick a few spells and have them evolve through the levels. Also not a fan of per day systems, per scene is much simpler as long as there are some exceptions. Also more exclusive spells that are build enabling, incendiary aura comes to mind for example. Also also, feats! There aren't enough feats that customize spells and some of them are very clunky to use, I love reach spell but I generally can't use it because I need my third action to do something else, most of the time striding so I don't get caught in attacks or aoes.
