Qt Designer: add a better way to position widgets in laid-out containers

I would like to ask you if possible, to add a better way to handle widgets both within Qt designer and Qt creator.

This current way is horrible when it comes to holding and dragging multiple items
inside the same container.As can be seen in the attachment, a good way, by the way,
already implemented in visual studio is, as soon as the mouse pointer is positioned
near the grid that this icon appears with several arrows indicating that I
can move everything inside without problems. sometimes

I get caught up in a project where I need to move several shapes and it's just annoying,
you can't hit where the red line is positioned right.
even if I click on the right side where my widgets are and try to move with the
arrow keys on the keyboard, it doesn't work properly, it messes up too much!
