While I have not used an Orange pi, my Rock 64 runs several 'programs' simultaneously and well. However it doesn't yet appear to have hardware acceleration for its Mali GPU, in Armbian, unless I am missing something.
Are there other graphical package managers? I'm also used to synaptic, but the 20 minute wait between searches is infuriating. apt-get install is fine if you know the exact name of the package.
