Samsung app broken by Nougat

[Dan Davies]

One of my favourite apps was one provided by Samsung, but I cannot even remember the name anymore. It was a replacement/enhancement for the 'Recents' function, and it gave that button much greater functionality. However, when my phone updated to Nougat, this app disappeared. I tried searching for the app, but without the name, that is very hard.
Does anyone remember the name?
If you remember it, do you know if it is coming back? Or a similar replacement?
