Based on her new power, I think she could develop being able to look into the past just like she does with the future, and at some point look and sense the world around her in the present, which could evolve into Astral Projecting herself the way Prue did in the original.
As an Empath she already has developed many abilities: sensing emotions, reading and manipulating thoughts, converting emotions to energy, manipulating peoples emotions, switching bodies. The only thing I can think of next, if her empathy expands even more is to channel peoples powers by tapping into the emotional energy it takes to control them (just like Phoebe did in the original).
