Right now in Sailfish OS when you create an app group by dragging apps together, the icon is a colored frame with a number in it and a group title underneath.
On Android and iOS the group consists of a transparent circle or square where you see the icons of four or more apps.
I would love to see the Sailfish group frame surrounding the visible depiction of (some of) the icons of the apps in that group.
The icons of apps like podQast, Amazfish and Talefish (and many more) all are nice graphical creations. It is a shame they cannot be seen directly when pulling up the app drawer if they are in a group.
