Almost there. 0.7.0-pre3 now has the whole tap-to-switch-graticule
feature working. Meaning that if the graticule you picked isn't all
that useful to you (in the middle of water, inaccessible, illegal,
etc), you can quickly tap another flag and switch to that instead.
0.7.0-pre4 should have the wiki features integrated in (assuming
there's no showstopping bugs that require a pre-release beforehand).
After that, 0.7.0, the real one, will be all up on the Marketplace.
With brand new screenshots, too!
