(after testing)

Wel, it's officially official now... I hereby declare GRead the best Google Reader client on the N900, heaps above any grr version out there :-)

Browsing feeds & posts is a pleasure in landscape mode with the keyboard, and at least usable in portait.

At some point I thought "but why not add an 'o' (orientation) shortcut to toggle landscape/portait ?"... then realized what a stupid idea that was :-)

But here's another : maybe extend your "furtive" buttons system in view mode, adding, say, a circle in the middle between the arrows, that would swap orientations ?

Oh, and it's still missing "Fred mode", of course... but everyone needs to sleep, right ? :-)
(I'd try to add it myself, but then I'd have to redo it every day !)
