[chimerax-users] Opening mol2 files with ChimeraX without ViewDock windows

Dear Developers, Is it possible to change the default behavior of ChimeraX when opening files in mol2 format to not showing the ViewDock window? I know I can add "showtool false" on the command line or make an alias, but I often open multiple mol2 files directly from the linux command line (chimerax *.mol2), and then the screen becomes cluttered with ViewDock windows. Alternatively, is there a command to close all opened ViewDock windows? Thank you for your help, Ute
