GriP 0.1-11m (r323) is released, and can be downloaded at http://code.google.com/p/networkpx/downloads/detail?name=hk.kennytm.grip-0.1-11m.deb.
The biggest change in 11m is the support for "Modal Table View". You've Got Mail has been modified to support this. The new mail message now looks like:
Note that the "detail disclosure button" is not there. When you tap on the message a table will pop up:
You can click on each item to view the message (not as ideal as MobileMail.app, but still readable):
Why is this change? My rationale is that, if you want to show the detail, you are focusing on the message, and stuffing that much information in that message is not good. If you're focusing on it, why not maximize the view? Hence it is shown as a "Modal Table View".
Does this contradict with the philosophy behind GriP (unobstructive)? No, because this modal thing already has user confirmation, while for alert boxes they just pop up with no prior consent.
(If you don't like this, you can always downgrade to 0.1-11k available in http://code.google.com/p/networkpx/downloads/detail?name=hk.kennytm.grip-0.1-11k.deb.)
