Gmail automatically sorts all the contacts based on your most frequent uses. But if you don't find that name at top, then you might consider saving a new contact.

To view a complete list of your most frequently mailed contacts, click Gmail at the top-left corner of your Gmail page, then choose Contacts. Next, click Most Contacted.

When you’re composing or replying to a message, hover over a contact’s name to see the email address associated with it, and double-click a contact’s name to edit it. If you have multiple email addresses linked to a contact, you’ll see your contact’s email address as well as name.

How can I change the order of suggested contacts in GMail app?
This is something it will be useful for several things now that I started "photoshoping" - so I made some lines with the pen tool, then right clicked with the 'direct selection' and then 'stroke path' to paint the lines. 

Now, this lines are closed, they make a shape, if I paint the inside with the bucket tool it creates white spaces inbetween the border and the filling!

How does one fill properly in photoshop?
