Porto Visualizer retracts a lot when I am trying to select something.  It seems like areas inside of the visualizer control panel when hovered over make the styler retract away.  I have to sometimes find a path that allows me to get to where I want to select in the screen with my mouse.

I suggest the idea of putting a way to pin the styler open for some long term edits to a theme. So it does not have to be opened over and over.

I also wish the styler color picker was a little quicker.  You have to click then move the mouse around to get it to start picking colors instead of just clicking on an area and it instantly appear.  If you have color code entering it in is fast and quick, I just always get an issue with the styler retracting a lot when I want it to stay open for a long duration.

This could act very similar to how the DNN Persona bar works with an X to close it once it has been opened or the save button is clicked.
