Xperia owners will be pleased to hear about XDA forum member xeviro‘s Gmail for Timescape plugin.
The plugin will show Gmail messages from all your Google accounts, although due to Gmail application security restrictions, it cannot open the Gmail app directly to the specified conversation.
For the current version, note that no contact images will be displayed since senders of emails may come from a lot of sources other than in your contacts, making the processing of each mail to show contact images costly on the battery life.
To install, go to Timescape service settings, then enable the Observe Gmail Changes. Note that the plugin will not work if you are running Gmail version 2.3.5.
Gmail for Timescape plugin is available to download free in the Market.
