Just a quick shoutout for people using Xubuntu and having trouble consolidating everything onto one taskbar/panel…
Xubuntu has an invisible spacer on the top panel to keep the system tray and clock plugins all the way on the right. If you want to have the tasklist take up all avalible space on the panel, you will need to locate and kill this spacer, otherwise it pushes everything on the right side of the panel off-screen.
The great thing about this spacer is that you have no idea that it’s there, you only find it by observing the wacky behavior of the panel when you re-arrange plugins. I would suggest that the XFCE developers mimic Firefox, and show a white box or the text “spacer” or something in edit mode to let the user know that there is, in fact, something on the taskbar that they can’t see. I only found the spacer by moving everything on the panel to the extreme left and right clicking on a whim.
Huzzah for usability! Tune in next week, when uncle Frem shows you how to make a complete desktop environment using only forty-eight thousand dollars and your teeth.
