Great app to filter contacts

We use Pobuca as our main database. We migrated all our contacts from Outlook into Pobuca, and are engrossing it as we speak. We have had, however, I do have some issues with it. It freezes quite often and does not have an alphabetical display to go to all the "f"s for instance, so you have to scroll down until you reach the desired letter. Merging contacts is also a bit rudimentary, you have to choose at least 2 contacts to merge, then scroll aaaaall the way up, for the merge button to appear at the very start of the contact list, so this takes quite a bit of time if you have more than a few duplicate contacts, and with the freezing, this takes up a lot of time doing. The rest works fine. The business card scan feature should work better also, some fields are not captured appropriately.
