Limit the size of the uploaded content per user

Hello dear WP Lovers

This plugn is pretty nice and it does actually only this simple function which is very nice.

But i miss there a restriction which allows admin to limit the amount of pictures or even better the size of all uploaded pictures to a maximum. at the moment the user can upload everything, somehow not so nice if only one user could fill up the entire disk on your server...

Is there any solution for that? I tried it with a wordpress function and a filter it worked good for the general upload in wordpress but it doesn't affect the buddypress activity plus plugin.

Would be glad to have such an option/restriction on the settings.
