An addon is run where the catalog lists it: on the Proxmox host, inside an LXC chosen from a list, or wherever is chosen when it can be both. The LXC is started when it is stopped, and OCI containers are left out. Until now every addon ran on the host.
A script is downloaded whole before anything runs, so a failed or empty download runs nothing. Descriptions and notes the catalog writes in HTML are shown as plain text.
The menu opens one script given as argument, and is as tall as the main menu.
