I like and use Aperture a lot, but realistically is still a v1 program. So I am looking forward to v2. Here's my wish list ....
1. Plug In suppport - Nik plug-in's etc.
2. iLife suite integration without duplicating photos or relying on Automator
3. Integration to FCP suite ..... since the photos are in a package!
4. Ability to use Spotlight external to the package ... or get rid of the package and just move to either file/folder structure or go to an indexed "RDBMS" database (yes, holy wars on this one, I know)
5. Burn archive of import, as a workflow element.
Multiple aperture libraries selectable from the File dialog vs. preference and then quit/launch
6. Span aperure library across drives
7 Standard max/min/lozenge buttons on windows and fonts that an over 50 year old can read .... or adjust .... on today's 23" or 30" high res. displays.
8. oh, and did somebody say .....
S-P-E-E-D?
speed
SPEEEED
9. ....but at least give us progress bars when say, moving photos from project to project
10. Undo on deleting a project .... you're into re-importing from the Mac trash can after figuring out which photo you need (yup, I have the scars and wasted time award)
11. Better visual representation of what's happening (or not) when trying to move photos across albums etc.
Either give us full line camera RAW support, or DNG linear support, or a plug in capability.
12. Overlay one photo on another in book view (tools to increase transparency/reduce saturation on the background photo to create a sense/theme)
12. CURVES!!

tool
13. Loupe tool that will stay over the photo while I use the mouse to alter tool settings
14. .... and Luddite that I am, I do still need a <Cmd>+ / <Cmd> - zoom function along with the loupe.
Here endeth today's list. And my thanks to Joe and the Aperture development team in advance!
