I'm very happy to use my Mozilla Thunderbird e-mail client for mail. I also use the calendar plug-in called Lightning. Lightning is connected directly to my Google Calendar account, so I can view my calendar live. I use several calendars on Google for different purposes. I just need a Todo thing on Google, but I solved that by creating a local account for that purpose.
Allright then. What is the new ?
I just discovered that it's possible to drag-and-drop an e-mail from my inbox to one of the panes on the right hand side. If I drag it to the calendar part of the pane, the mail is copied into a new calendar event. If I drag it into the task pane, the e-mail becomes a task.
I love open source !
