While doing some udisks development and testing with Thunar, I've noticed Thunar doesn't bring up very helpful device removal messages. Currently, when the eject icon on a device is clicked, Thunar brings up a notification (thunar/thunar-notify.c function thunar_notify_unmount()) with: ``` Writing data to device There is data that needs to be written to the " "device \"%s\" before it can be removed. Please " "do not remove the media or disconnect the drive" ``` which has an infinite timeout. Then, when the unmount is completed, thunar_notify_finish() reduces the timeout to 2 more seconds. Then it just disappears. The user is never told when it is safe to remove the device. glib's gio's GMountOperation has the "show-unmount-progress" signal since version 2.34 (released 24 September 2012). These tell us what messages to show the user, and at the end we get one with: ``` [Device] can be safely unplugged Device can be removed ``` It delivers this with i18n already applied. We should probably use it.
