I am using Ubuntu 18.04 with GNOME desktop.
While safely removing an external hard drive (or USB stick), Files does issue notifications as stated in the link below (“Writing data to … Device should not be unplugged…”). Once the data transfer is complete, the message for safely removing the device also appears normally.
But these notifications are so tiny and silent that it is easy to not notice them. The risk of not noticing them and removing the drive prematurely by mistake is obviously high.
Is there any way to customize these notifications to make them appear more boldly, and with a audible tone?
