People used to create a transparent icon for the notification and use priority settings to push it to the end of the status bar, giving it the effect of it not being there. I believe trying to get that working reliably over all versions of android and all device types is now practically impossible.
Thanks for your time.
If realent is complicated, the issue is that for certain applications it is a bit invasive, and it would fill the icon bar when it has 3 or 4 applications running, because that icon cannot be removed.
I'll try to see what I do.
