well, it won't help you today but.... I liked/needed Progect so much I wrote a version for the Zaurus at http://www.janerob.com/rob/prozect , and I fully intend to port it to n800 (all free this time) ... which hopefully arrives with my sis-in-law around the 27th june :-). prozect depends on the qt tree widget code, hopefully there is something similar to work with in gtk+.
