Gmail has been offering subtle updates lately, which include auto-complete in different languages, among others. One of the latest updates may not be so visible, but will be important to Gmail power-users. The popular cloud-based email service now offers autocomplete in the advanced search function.

The added functionality will auto-complete while you type in the From and To fields in advanced search. While this same functionality is actually accessible from the default search box in the inbox view, having auto-completed email addresses or names will come in handy when doing targeted searches.

Aside from autocomplete, Gmail has also “graduated” three new features from Labs. These are:

• Refresh POP accounts. This feature is useful when you manage multiple inboxes and external accounts from within Gmail. The refresh icon now let you manually poll your POP accounts for new email, instead of simply forcing the Gmail inbox to refresh.
• Filter import/export. This functionality lets you download your filters or upload a set of filters in one go. This will be particularly useful if you manage several Gmail accounts and want the same sets of rules.
• Navbar drag and drop. This lets you rearrange the navbar content simply by dragging and dropping.

Come to think of it, these are simple features, but are very powerful — or at least convenient — when you know how to properly use them.
