With R5, the Tracker gained a very useful feature that lets you see at a glance where you are in the filesystem. Tweaking this setting will enable display of full pathnames in Tracker title tabs, rather than just the current folder name.

To enable this feature, open the file /boot/home/config/settings/Tracker/TrackerSettings and change the line

ShowFullPathInTitleBar off

to

ShowFullPathInTitleBar on

After saving the file, you’ll have to restart the Tracker for the changes to take effect. This is important, because otherwise changes will be lost with a reboot. The easiest way is to invoke the Team Monitor by pressing CTRL+ALT+DEL. There you kill the Tracker, activate the Team Monitor again, and press „Restart Desktop“ to restart Tracker and Deskbar.
