This may end up going into the core as a preference.
I basically would only have to make a few minute adjustments to the drFileDialog file.
Just to be clear, there are two features the DrPython file dialog currently lacks:
1. The ability to read windows .lnk files.
2. The ability to access network files.
The current wxPython dialog handles both.
I know at least on the Windows XP platform it works correctly. Haven't tried the demo on linux.
Just tried out on Mandrake, current file opener doesn't support symbolic links or kde folder shortcuts either. I would guess that the default wxPython dialog can, but I don't have the demo on this comp (doesn't come with package)
