[Feature request]: Access to other settings while using "Test Image" page

[Squall1er]

Is your feature request related to a problem? Please describe

When you are on the "Test Image" page, the software is hide.
It prevent you to make ajustement in "live". So you have to get out of the page and wait for the software to be here again.
Also the animation is taking half a second to make the software come back.

Setting everything take much more time, expecially for the first time when you are testing different parameters.

Describe the solution you'd like

Be able to use the software while in the "Test Image" page

Describe alternatives you've considered
