You can control the launch of composers and create your custom services and scripts. I have remnants of such experiments in respin with running picom through custom services.
I think the point raised by OP is that something that used to be simple, such as specifying in desktop startup to run something, now in antiX it became more complex.
Perhaps now for that example being volumeicon, you would need to create a user service to start, along with all the service requirements.It may be a better way but the original simplicity of such things in antiX is gone.
antiX becomes more sophisticated and this is good but less technical users might be harder to convince that they should learn to create their user services, while in the past it would be just instructing someone to add a line ‘sleep 10 && volumeicon’ in the desktop startup from the Control Centre…
In antiX, that’s exactly what dinit does! Instead of custom services rc.local and put your ‘sleep 10 & volumeicon’ there
