First you’ll have to enable the feature in Google Labs:

You’ll see a new tab within your settings where you’re allowed to change the displayed inboxes. In the example below I’ve created a box displaying my mails labeled WICHTIG (German for important) and TODO. Notice the operator OR which will display mails with either one of the logos. More information on these operators can be found here. Other possible operators could be

is:unread
has:attachment
bcc:YOUR NAME
is:chat


The second box will display all starred items.
Notice that you can also set how many items will be displayed per box [Maximum page size]. You might want to use a small to save some real estate on your screen.

The last options will let you set the position of the box, which is a matter of your personal taste [Extra panels positioning]. I prefer the box on top of my regular inbox.

And this is how your new front interface will look like. I really like the idea how this draws my attention to the TODO and WICHTIG labels every time I check my inbox. (In the screenshot below I changed the maximum page size to 4)

I really like the new feature… Gmail is getting better and better every day.

The options are quiet simple but for me it is all I need like categories, due date and notes.

Another cool feature I already know from Apple Mail is converting Mails into tasks.

GMail’s to-do list is a labs feature. To turn on labs switch your account to english language and enable labs in the setting menue. Under the tap “labs” you can enable all available labs-features.
