I couldn't find anything about this on the bug/feature request site.. Is there a TODO (or if not, why not) about writing/loading all K:'s to a config file? ie: adding an expiry field to the config, writing the config entry when one is added, removing when it expires..
Currently I'm using services to handle most of them.. I have seen a mod to make perm ones written to the config, but for temp ones (and then updating to the latest version) they are (of course) lost until re-set.
