@ievolver  (Ref #211 and #213 ) – I think we can go with two iconsets only. The first iconset could have icons with dimensions of 92px, and the 2nd iconset might have icons at 64px.

The space available for each grid item will be calculated at run-time, and the icons could be down-scaled if necessary.

I thought the best grid configuration is something like this:
OS7: Quick Photo – Posts – Comments – Page – Stats – Reader – Options – Dashboard – Refresh
OS6: Quick Photo – Posts – Comments – Page – Stats – Options – Dashboard – Refresh
OS5 or lower: Posts – Comments – Page – Stats – Options – Dashboard – Refresh
(Quick Photo could be added on OS5 devices in the next app release)
