General information

• App version: 68c534a94776bf3a8c00b3f02f7ac421d38f5e2
• Android Version: 7.0.1

Expected result

What does happen? Currently only the "circular reveal" animation is supported.

What is expected? To have support of more animations when showing the app grid.

For myself the most important would be e.g. the Zoom Animation, you can see the animation below of e.g. Nova Launcher:

Just as a comparision, this is available on Nova:

• Zoom
• Circle
• Circle wipe (this is our current one)
• Slide up
• Fade
