For you, what is the most needed (but missing or poorly implemented) application for the N770? For me, it is the woefully inadequate email client that is included with the 770. What are my issues with it?

First off, the ui is incredibly inefficient for dealing with large volumes of email. I haven't found a way to choose which header columns to display (and in what order), resulting in only partial display of critical information like From and Subject. Secondly, there is no easy way to select multiple, particular items for deletion. I can select all, but that isn't very helpful if there are actually some items you want to read amongst that sea of spam. How about a simple checkbox next to each message, like webmail has been doing for years and years. When I do click the delete/trash button I get a prompt about deleting it from just the device or from the server as well. If I select server as well, it connects right then and there to do it. Having to go through this process for multiple messages is quite simply a pain that has made the 770 useless to me as a mobile email platform. I have taken to carrying my six year old Jornada 720 with the excellent qmail3 email client along with me when I travel for any length of time. The Nokia 770 is a very interesting device in a lot of ways, but is surprisingly bad as an "Internet Tablet." Frankly, I would have expected a higher degree of useage refinement out of Nokia.

So, what are your most requested/needed applications? I get frustrated when I see a lot of development time going into very niche use applications when a lot of basic, common needs being unmet.
