Yup, everything's already there, just a bit disguised:
* Feed before original site? No problem, set Feed as the default in Preferences. Also, if you like one view or another, it saves per-site.
* To read all stories in a folder, just click the River of News icon next to the folder. It's exactly the same. You can also right-click the folder (or click the little arrow) and mark the folder as read.
* Plenty of Keyboard Shortcuts. Type `?`
* I'm working on more customization of the interface as we speak. You'll be able to move panes around, change sort order, etc.
I don't see a mark folder as read shortcut (did I miss it). I can context click on the river of news icon, but I'd love a button (and shortcut) next to the "Next Unread" in the dividing bar. I wouldn't text an icon button would do to save space (maybe a preference shut off text in toolbars)
