That would be great... i am not familiar with creation of patch files but fortunately i can probably just tell you...

The only file i modified is Transmission/gtk/tr_prefs.c of the source i posted :
- lines 38 & 44 (tr_prefs_init_global function) is where i change default dir and disable systray minimization
- starting at line 215 (tr_prefs_dialog_new function) i begin a series of block commenting to hide less important settings from appearing in the 'preferences' dialog.

I doubt you even need a diff tool but just diff that one file (tr_prefs.c) to the upstream version.

Also (if you know) could you tell me how to build straight from subversion. svn doesnt include makefiles and autogen.sh fails because scratchbox is missing intltoolize.

gerbrick : sorry i missed your question; the icon size is the same as previous releases but since 2008 supports larger icons i may have mixed the two up. whats it doing?
