When a ruin is in status "Explored" it will show this, and no info about what monsters/items was there previous.
If a pre-set ruin is respawned, it will just show the standard random monster info popup.
The items (most of them i think at least) will come in the next upgrade. We havent started any serious work on them yet as we want 0.8 to stabilize a for a few days first before we branch of and start work on next version.
Sorry for vague answer, we will come back with more info on them soon
