Potential duplicates in the quick information presentation in web client

Hello,

I want to avoid users to create duplicate work items because they didn't take a look at what is existing.
And I found something really great for that : displaying potential duplicates (as you type) in the quick information presentation.
But this feature is only available in Eclipse Client.
And my users are mainly using the Web client.

Did I miss something about this feature ? Do you know if it is planned in the future?

Do you have other automatic ways to prevent the duplicate work item creation ?

Thanks for your help,
