Early versions of MacOS had a simple way to launch applications: All of your favorite applications icons appear in a rectangular window that is always present.

This is just a sticky window with icons for each icon and a horizontal scroll bar. I could not find screenshot, but it looked similar to the icon manager app from Motif seen here, except that in Motif, this program is a taskbar, not a launcher.

Are there any apps like this? Closest I could find are some application launchers that fill up 90% of the screen, even at high resolutions.
