You're adding an additional taskbar. That's a huge waste of space since the original (vertical) taskbar in synth's Turbopup Xtreme acts as *both* a launchbar and a taskbar with a system tray.
With synth's taskbar,if you open some programs / windows, small tabs are placed under the shutdown icon (that's the vertical taskbar area) , wasting the least space possible.
Synth's Turbopup Xtreme has the most efficient taskbar design I've ever seen in a Linux distro
