LinuxQuestions.org - GTK File Chooser Dialog Box Side Panel Behavior

In both Slackware 12.2 (gtk 2.12.12) and Slackware 13.1 (gtk 2.18.9), the left-hand side panel of the GTK file chooser (File Open and Save) dialog box displays three sections. The first section contains two options: Search and Recently Used. The second section contains several options. The third section are personal bookmarks I have created and stored in $HOME/.gtk-bookmarks.

Modifying the bookmarks section is straightforward, but I am searching for ways to modify the first and second sections.

1. In both 12.2 and 13.1, the second section shows the following: $HOME directory, Desktop, File System. In 13.1, several mount points now appear. I think the criterion being used is the mount point being outside the main root tree. Several of these mount points are configured in fstab with the noauto option and are user mounted only as necessary. I do not want any of these volumes appearing in that section nor the Desktop option. Is there a way to exclude those volumes and options?

2. In that same second section are two mounted volumes from a second internal drive. Those two partitions are part of my bookmarks. In 12.2 those two partitions appeared in the bookmarks section. In 13.1 those two bookmarks are ignored and instead appear in the second section. I prefer those two points appear in my bookmarks section because I prefer my own labels rather than mount point names. Is there a way to do that?

3. Is there an option in $HOME/.config/gtk-2.0/filechooser.ini to control the width of the side panel?

I have been searching the web but to no avail. :(

Thanks again.
