PRO TIP: for the safety of your bookmarks please backup them before the very first use of the extension - howto: https://support.google.com/chrome/answer/96816?hl=en
Why? Actually the extension removes (not simply hides!) titles from the bookmarks and stores them in Extension's memory for future restoration. It means that if you use Chrome Sync, bookmarks on your other devices will be affected. If your Chrome crashes for some reason, it's possible that you'll be left without a way to restore bookmark titles. You've been warned ;).
PRO TIP 2: before uninstalling the extension (but why would you?!), use it to show the bookmark titles back. Otherwise the titles will be lost.**
