modifying the gtk file selector

[wino piments com]

I use a number of good programs which are gtk based: gimp, gftp, bluefish  
but I find I am continually hindered by usablility of the fileopenDlg.

I gather this is a bit of a contentious subject and that there is little  
chance of getting any official changes in the way this works so I have  
decided to get in there and at least remedy some if the things that bug me.

I have three areas I want to look at, from trivial to _big_job.

1. When I select show hidden files I want to see '.' and '..' , the first  
gives me a refresh capablility the second a consistant way to move up the  
file system

2. If I change into a directory with a lot a files it takes for ever to  
log the directory and there seems no way to break out, I just have to wait.

3. This is the biggy, I want a tree view not bookmarks in the left panel.  
The file system is a tree structure. I need to view it in that way to work  
efficiently .


So can anyone point me to the relevant files to save me a bit of digging,  
I am completely unfamiliar with (wx)GTK et al

Am I right in thinking that none of these areas are being tackled and  
this  is pretty much a closed subject as far as the developers are  
concerned?

TIA.
