1Password for Mac, the popular password management app that we love here at 9to5Mac, has been updated to version 4.1 with a huge list of improvements, fixes, and additions. The first of these new additions is a new multi-column display mode with customizable column sizes.

One of the key changes to the app’s browser plugin is an updated auto-save system for new logins. Whenever you enter a password on a site you haven’t previously saved, 1Password will offer to store the password for you. With today’s update, you’ll now be able to use this feature to update existing passwords that have been previously saved. You can also tag your new auto-saved items right from the auto-save panel.

Also new with this update, you’ll now be able to set any custom field as a password field in the app. That means the contents of that field will be hidden by default just like it would be for a regular password field. You can then search these fields—and all fields in every saved item—with the updated search function.

Other tweaks and updates include the ability to print out your entire list of saved items (be careful what you do with that list!), security enhancements, bug fixes for issues with syncing, and more.

The update will be available this afternoon on the 1Password website, and is currently in review for the Mac App Store (Update: available now). You’ll also want to grab the iOS version for keeping your data in sync between all of your devices.
