* fix unapi in umlaut. unapi to rsi? For zotero.
* Change background to use Spawn plugin instead of manual threading. Investigating using spawn with fork instead of thread (terry reese on limited pool of forks).
* Integrate my various local document delivery services into menu of options when full text isn’t available. More generally, a clear architecture for providing localized doc delivery services in addition to a single ILL link.
