That's what I see in the game interface if I start ARMA without joining a server, but in the lower left corner. In that case, there are three rows of icons. Row 1 is DLCs I don't own, row 2 is DLCs I own, and row 3 is mods that I have loaded. Row three starts with a puzzle piece that opens the Steam Workshop. In my case, there are two icons to its right; Enhanced Movement (a blue cube), and JSRS (a microphone jack). The interface that I was referring to was accessed by first joining Tac 1. While you're looking at the world, press ESC to see the ABORT, RESPAWN, etc, menu. In the lower right corner of the screen will be a puzzle piece that allows you to configure any loaded mods. I wasn't aware of the icons on the game start screen because I always use the ARMA launcher to immediately connect to a server.
