Desktop entries

Improper association of launcher with running window
Run this, then focus the desired running window 
 xprop WM_CLASS
 
 The output will be something like 
 WM_CLASS(STRING) = "MATLAB R2024a", "MATLAB R2024a"
 
 Then in the desktop entry, add: 
 StartupWMClass=MATLAB R2024a

Improper opening of links in browsers
add %u after the exec utable in the .desktop entry

Dolphin
File gets opened instead of showing directory 
 Use the --select option with %f 
 --select shows the containing folder and highlights the file passed with %f 
 
 ⚠️ I thought this worked, but deleting the custom desktop entry worked better...

Improper opening of apps on KDE
An issue where the window does not get stitched to the instance being loaded and in some cases, opens a new Wayland window with the default yellow logo. 
 The fix 
 StartupWMClass=zen
 
 inside the .desktop entry (solution shown for Zen browser)
