GApp - Lightweight, configurable, interface for GMail and the Google Apps for people that live in GMail
Version: 0.2GApp is a lightweight, configurable, interface for GMail and the Google Apps for people that live in GMail. For those who use GMail labels for Getting Things Done (GTD), GApp provides a searchable GTD view of your Inbox.
Operating System: Mac OS X
The clean, lightweight interface helps you keep focused on the task at hand, without the distractions and extra functionality of working in a fully-fledged web browser.
The application leaves all your messages on the GMail server and is based on WebKit, the engine behind Safari. So you can switch to another computer knowing that all your mail is fully accessible.
NOTE: GApp is free software, developed under the GPL. Please encourage the continued support and development of the application by donating to the project.
