Fine with either. 
Tagging VDG. They can make a decision.

As in most applications circle mean peopel/user/artist/contact/... I would say sure. from my point of view I had the problem that circle mean also that you remove a lot of content in difference to square, but as I wrote it's kind of standard to have humans in a circle.

e.g. at music player apps you have albums (square) and artists (circle). and there are a lot of other examples out there.

I like what I see, I think it is more pleasant than a squared avatar. I approve.

Well a circle avatar is already possible. The dark avatars for example (konqi, penguin, zebra) are nothing but PNG images with transparency (done in GIMP iirc and you can do that now by placing a circle around whatever image you want and then cropping the image, saving it as a PNG with transparency (which creates a square image but with content only within the circle) and loading that from file).

I think removing the option to have both is not a good way to go - instead being able to set "round" or "square" may be relevant but that should be a technical decision as it's pushing demands for further options to the devs.

I think the idea here is to automatically crop square images to a circle, which is what the Breeze themes for KScreenLocker and SDDM do. Right now there's an inconsistency, because Kickoff uses square avatars instead. We should decide on a single one (circle or square) and use that everywhere.

My vote is for a circle, FWIW.

That patch got stalled. I think anyone else who's interested in working on this can take it over or have a go at it.
