Admittedly, I would like to see more billable programs for Linux.  I have 
tried Gnu Cash but I find it a bit cumbersome for simple time tracking and

use Adobe programs in Linux.  Obviously this is not a Fedora gripe but an 
Adobe one.  I am confident that as Linux desktop adoption grows, Adobe 
will reach out to this market and provide products.  It already has with 
Flash and Acrobat.  I am also a part-time web developer and use Flash, 
Dreamweaver, Photoshop and Illustrator.  It would be nice to not have to 
boot into OS X use these tools.
    

You might want to look at Knomos:

http://www.knomos.org/index.htm
http://sourceforge.net/projects/knomos

However, it appears development stalled once they reached the 1.0 or
1.0a version -- I assume at completion of the contracted work.  It
would be nice to see additional development by people who care about
it...
