First: if I select in Settings to hide the Taskbar, and I hit the windows key, only the start menu will pop up not the taskbar.
Second: the system tray is a variable thing, you start an app and that will reside in the system tray until you close it so it so I don't think you can create a dock that will cover that.
Also there are apps in the system tray that are also launchers, like Steam, where you don't need to open Steam to open a game.
So any workarounds might be welcome but what is the point on having a launcher on top of another launcher, which also consumes your resources for nothing.
Thank you,
