I like to pop out my timeline in AFX, to have it side by side with my comp viewer as i have an ultrawide monitor. I normally just draw this window out to be roughly half of the screen.
This is great asd i can use the ~ key to expand and solo either my comp viewer, and/or my layers, and it's brilliant.
The undocked panel that After Effects creates though, doesn't work with the PowerToys FancyZones feature. When i'm using Windows Powertoys to snap the main AFX window to half of the screen, it works fine. However, the other UI window with the timeline cannot be snapped.
At first I thought this was an issue with PowerToy's FancyZones, but it was updated to allow 'child window snapping'. This works really well with Cinema4D for example, where I can snap the picture viewer into a zone that is separate from the main program.
Seems like a bug with AFX?
