As part of a raft of small changes to Gmail (s goog), the app now has the option to disable its automatic saving of contacts. While many people find the ability find the automatic saving of any recipient a message is sent to to Google Contacts useful, for some it ends up creating too much clutter in their contacts list.
You can disable contacts auto-save in the “Create contacts for auto-complete” section of General tab of the Setting screen, as shown in the screenshot below.
Note that Gmail uses your contacts list to auto-complete email addresses as you type them in the address fields, so if you disable auto-saving, you’ll need to make sure that you manually add any email addresses that you’d like auto-completed.
Other useful changes to the product include better warnings for typos in email addresses and letting you know which email address contains the error; a reduction in annoying pop-up messages; and easier access to keyboard shortcuts — the Shift+? shortcut, which brings up a keyboard guide overlay, is now turned on by default, and also includes a link to enable the other keyboard shortcuts.
