No problem, I was also busy so the coincidence is pretty great :)

You're right, it doesn't work on the "Frame" part. This is only a
field lacking in the XML layout file, you can see that it works for the
position/vector fields for orbit definition.

The problem with latitude/longitude/altitude fields is how to manage
favorites in term of user interface. Here everything fits, and the
number of clicks required is not so much since there is not a lot of
fields. I really don't know how to do using these fields, but if you
have a solution which mixes favorites management as well as the "Fetch
current coarse location" so it can not feel strange, I'll be happy to
implement it :)

Ok :)

About editing, it was just because you can edit by selecting a
favorite, re-click on "Configure", delete your old, modify the settings
and save it. But I understand it's not very intuitive :)

No problem for not pressing "OK" directly.

OK.

Ah. "black" problems shouldn't happen with the scrolling part, can I
have a screenshot ? (you can make one by plugging your tablet, and
launching "ddms", a tool present in the Android SDK)

On my phone, eclipse events are gathered in a single row. But maybe
I've not commited some changes.
