The info screen's Resources table shows Autostart (yes/no), Startup (order, up and down delays) and Tags. o opens a dialog to change them. Only keys that differ are sent, in one `set <kind> config` call through the existing set_net. A confirm lists the old and new value of each key. Tags are removed with `--delete tags` on set config. The CLI also has a `delete ct|vm ... tags` command, but it shares the form that destroys the whole guest, so the app never uses it; nothing in the code builds a delete ct|vm argv. Inputs are validated before sending: startup values must be ints >= 0, and tags must match [A-Za-z0-9_][A-Za-z0-9_+.-]*. They are split on ; , or whitespace and deduplicated. Live test on CT 104: onboot 1 -> 0, startup order=5,up=10, tag tui-test added, then all set back through the dialog. The config ended identical to the baseline.
