A new year is coming and with it a new iteration of iWork (and iLife). Personally I use Keynote a lot and have high hope for the next version. Pages was a real disappointment, so there is a lot of room to be made up. Also, there is a good amount of buzz around a spreadsheet app being added (Numbers). So what do you want to be added to iWork '06?
Keynote 3
Watching Jobs' last few presentations I've noticed new transitions not included in Keynote 2 (like a vertical blinds transition). I'd like to see some new standard themes in Keynote 3 as well. Once feature that isn't really supported out of the box is decent iPod integration. By this I mean being able to load a Keynote presentation onto an iPod and then use the iPod AV outputs to run the slideshow with a projector. With the new remote control and dock, this should be a little easier (although having an IR remote might not be the best option). Since the new iPod support video, this sort of Keynote-iPod integration should also support animated transitions.
Motion graphics and moving templates would also be a welcome addition to Keynote, especially for kiosk displays. Being able to add animated text (flashing, wiggling, changing fonts randomly, etc.) would be cool too. These features might not be great for formal presentations, but they would be a welcome addition. Basic equation support via a LaTeX 3rd party app is fine the way it is, but integrated support for LaTeX equations (and possibly more) would be great. Beyond a new assortment of themes and transition, a wider selection of pictures and objects for Keynote (like those found in /Library/Application Support/Keynote/Image Library). Having a set of chess pieces is nice, but how about images of PowerBooks or iPods or other computer related objects.
Number 1
As for Numbers, basic spreadsheet features are a must. The graphing/plotting features included in Keynote now are just too limited. Beyond simply mirroring Excel, though, Numbers should be able to call upon the graphing capabilities of the Grapher app already part of OS X. This would allow Numbers to work with discrete data sets like Excel and functions like Mathematica (although probably not nearly as well on either front given this would be a version 1 product). Hopefully, though, Apple learned its lesson about releasing software before its ready after Pages all but killed iWork '05.
Pages 2
Pages needs the most work. I'm voting for more LaTeX support for text layout (buried underneath a standard Apple GUI, of course), tight integration with Numbers for graphs, plus better Word importing/exporting. the .doc format has moved to XML and is more open now, so support should be easy to add. Pages could also benefit from a larger template library. Keynote has the benefit of a large user community creating new themes every day, but Pages is left out of this. Apple needs to step in and fill the gap.
Even with a new app like Numbers, I really hope iWork '06 stays under $99 (or at $79 like now if possible). I already have a feeling that iLife might hit $99 if they add a remote, and I don't like how that bodes for iWork.
