Thanks for a great aggregator!
Here are my trivial additions up until now:
to the end of WinGUIMain.PopulateTreeFeeds to expand the feedtree after loading.
or any other convenient shortcut in ShortcutSettings.xml so that Alt+F4 minimizes RSSBandit instead of shutting it down (applies to when Minimize to Tray is set to "On Application Close").
Just some suggestions. I hope to add more as I come across them. Keep up the good work.
