I’ve just purchased Pro today and was about to ask the same question. If we haven’t purchased E-Sign, then what possible justification can there be for it taking up real estate on my tab bar, of all places? It’s a little annoying and distracting, and it really belongs in the E-Sign ribbon area, not cluttering up my work area. I can understand that moving it might require some development time, but surely a patch to make it disappear entirely is not asking too much? If you could, please pass this request along to the developers.
