A request by Bryce Yehl: "I'd like to configure Radio [Userland] so that it automatically runs the news scan less frequently, perhaps once per day. Coupled with that, I want buttons in the browser to scan immediately and temporarily disable automatic scans."
A few things that might help: Kit, a Radio Userland shareware tool by Mark Paschal, can be used to read the news that arrived over a time period you designate (for instance, I start each morning by using Kit to display all of the RSS items that showed up overnight). Also, if you'd like Radio Userland to scan immediately when you load the program, change the Scan on Startup? preference.
I've posted some follow-up to this on my web
site. It seems that both of these wishes are
easy to accomplish.
