It would be helpful if in v 4.0 the resources could be zoomed at a variable rate rather that at certain fixed increments. This would be helpful in trying to line up the text of a targum with the BHS text.
Also, in certain dialogue boxes such as notes selection or "Define Collections" it would be helpful to have an entry box such as that in "My Library" (I don't know about "Your Library") which would allow the entry of the title of the item to be selected so that it would not be necessary to scroll through the list.
