When adding an activity to a profile the pop-up box blocks the contacts profile, limiting the information you can see from the persons profile. It would be helpful to have a more transparent box that would allow to both the individuals profile and add the content of your activity, phone call, etc. at the same time.
Alternatively to be able to drag the pop-up box to another part of the screen or to independently scroll the behind screen containing the profile information so you could move the screen to see the information you needed.
Also perhaps an icon in sidebar popup windows that would allow us to "unpin" that sidebar window and allow it to be manually moveable.
