My apologies if this idea has been suggested before.
Its a fact that we can't stop end user to install non-OPTfied packages, which results into info banner 'Not enough memory in target location' after installing few of non-OPTfied applications. So, for the benefit of user, can we make an application which will inform user about the rootfs usage by different 3rd party applications and suggestions to remove those overburdened applications.
I too technically challenged, might have understood above stuff wrongly. please excuse.
