This is a tool to preview Preferences dialogs designed with Erel's Tool FormsBuilder on one or more devices at the same time.
A practical way to see the result on different screen size, resolution and scale.

Strange situation with Camera2 usage for the video recording:

I haven't managed to replicate the error myself, however a user of mine has experienced it.
