Full Background Pop up transition

Some motion study going on for a current client. The study is about a pop-up transition. I find pop-ups annoying because they are very intrusive. I tried to make them more acceptable by displaying them as a full background, also to help users to be more focus on the task they have to fulfil with it.

I have used Principle to do this animation. I found it quite quick and efficient to give a feeling of what the transition could looks like without having to use a high definition mock-up.

Let me know what you think :)
