A 'Like' or 'Upvote' button

Hi all, just thought I'd suggest something that has been on my mind for quite a bit.

When I favourite a project its because I intend to somehow use it, and I don't think I'm alone on this. That's a great function of the site, being able to save all the projects I'd love to try in my favourite section. What I find however, is that there are plenty of lovely projects I'd love to show appreciation for or commend the creator for, but I don't want to essentially clutter my favourite section with projects I don't intend to try myself and I'm a little too shy to leave a comment.

Furthermore, its a little sad to see hundreds of projects on the site with 0 favourites that really deserve some appreciation! But I think that a lot of users are like me when deciding to favourite a project. In order to combat this, I think the introduction of a "like" or "upvote" button would be wonderful! There seems no need for an additional dislike button, because we are a supportive community who I don't imagine would discourage creativity or critique people with this function.

I just thought I'd put this idea out there (I'm sorry if it has been proposed before). The image attached is just something I whipped up in 5 minutes to show what this might look like.
