Kevin and I have come up with two different solutions for this bug: implementing it as a plugin and in GTG core.
You can try the core implementation at lp:~gtg-user/gtg/gmail-like-ui, which adds an option in the "view" menu.
The plugin implementation is available at lp:~gtg-user/gtg/customization_plugin/, look for a "Gmail-like interface" in the plugin menu.

Which one should we merge?
