I feel like all objects that will hold stuff (except for ender chests) should be moved under the container flag. This includes jukeboxes, ovens, and anything I am forgetting or will later be released to vanilla Minecraft. Could it be possible to have the access to ovens be dumped under the container flag instead of /res pset use? I'm building an absolutely massive city and would LOVE to be able to flag everyone /res set use so that i do not have to have an access sign over every door (will easily be over 300) and button due to the fact that they would otherwise be able to steal out of my ovens. If there is anyway this would be possible, it would be awesome.
Furnaces and jukeboxes are already protected by the container flag. The use flag protects doors, levers, shearing of sheep, etc.
