The toolbar option you describe is only available on Windows (#3)
How do you have KDE on windows...??
Stellarmate OS on Raspberry pi4b
Skywatcher EQ8 pro, on steel pier
Takahashi FSQ85 & Meade 8” SCT (de-forked)
Starlight Xpress SXVR H18, SXVR M25c, Lodestar x2 Guide Camera
Pegasus Ultimate Hub V2 for all USB & Power
Pegasus focus motors on both scopes
So the Windows and Mac versions will have the star profile viewer by default, the Linux version might or might not depending on your system packages. The Star profile viewer depends upon a fairly new QT module called Qt Data Visualization.
