I strongly agree. As an example try to create an Launcher for Eclipse, it is a usability nightmare.

Windows:

  Right click > Pin to Taskbar

Mac:

  Right click > Options > Keep in Dock

Ubuntu:

  gedit ~/.local/share/applications/opt_eclipse.desktop

  [Desktop Entry]
  Type=Application
  Name=Eclipse
  Comment=Eclipse Integrated Development Environment
  Icon=** something like /opt/eclipse/icon.xpm **
  Exec= ** something like /opt/eclipse/eclipse **
  Terminal=false
  Categories=Development;IDE;Java;
  
  nautilus ~/.local/share/applications
  chmod +x ~/.local/share/applications/opt_eclipse.desktop
