Here’s something that Facebook might want to emulate: a feature unique to Google+ that allows users to disable comments and “lock down” posts from sharing – before you actually share.

Mashable reported that previously with Google+, users were only able to disable and lock down after a post was shared.

“Now, you can do it before you share, which makes much more sense; after all, if you don't want anyone to comment on or share your post, you probably want it that way from the start,” the report said. In order to choose the lock and disable options, you hover over the share box of an item you want to share.

In a demo video, a Google+ Sharing engineer explains, “We’ve heard from many of you that you would like these disable-unlock before you share, not after. So today I’m happy to say we’re doing exactly that.”

In posting photos, for example, Google+ explains, “If you don’t want viewers to download your photos, click the gear icon on the top right corner of this screen, go to Google+ Settings and uncheck the ‘Allow viewers to download my photos’ checkbox.”

Many users are praising the distinctively Google+ feature, calling for Facebook to “pay attention.”

Mashable reader Jay Whiting commented, “Definitely an improvement on the old system. Small, helpful change (are you paying attention Facebook?)”

But another reader criticized Google+ for its exclusivity that leaves some users left “in the cold” and the company’s lack of communication about its social network.

The most dedicated and loyal Google users are left in the cold here. For me this is really unbelievable. Yes I also have a Gmail-address as secondary e-mail, but if you want to fully experience the true value of G+, which is integration, it’s totally useless. It has to be under your primary Google-account. The worst part is Google’s lack of communication about this matter.”
