This is app is great but...

I use this app for doing the drafts for my PMVS on my channel Lunarocks productions and I think its really helpful but... I always have to delete when Im not going to use it for a while because it takes up way to much memory on device which has only less than 2GB left and the thing is I dont have pictures I always import them to my computer and I have very little apps too, so if it would be possible you guys at Apple reduce the storage this app iMovie takes up PLZ? It would be very helpful
