One of these is changing a profile picture. I believe it’s a good idea to keep the same avatar across social networks. Attention spans are so horrible today that an easy identifier is necessary.
BlissControl can be a hub for the networks listed above and more! Not just profile pictures either. Change your password on Twitter, Facebook, and Instagram without having to remember where to go on each site. Especially handy since Instagram doesn’t have a login page from the website.
There are a few settings not supported yet (like changing a profile pic on Instagram), but it works pretty good. Save yourself some time with BlissControl.
