I think a valuable addition to the mod would be a level emitter that works exactly the same as the energy level emitter in base AE2 but uses the FE energy stored in the FE energy cells. I'm trying to automate antimatter production to only use excess energy in my system and as i'm using appliedflux as my main energy storage it would make things much easier. Another solution would be to allow AE2 level emitters to accept FE in the configuration.

I very much agree. There are a lot of features in various mods to use data pulled from storage levels (like a redstone signal based on the fill level of a Draconic Evolution energy core), and being able to read the FE storage levels in this mod would be fantastic to make various meters and fill info panels from CC and such.
