Keep "Preferences" > "Snap to pixel grid" while allowing free alignment for perfect centering

Hi

I want to keep ("Preferences" > "Snap to pixel grid") enabled, while being able to:

• Center a shape with perfect precision.
• Freely move a shape while snapping to pixel grid when possible.

Disabling ("Preferences" > "Snap to pixel grid") can be useful when trying to perfectly center a shape inside another. Examples:

• https://forum.figma.com/ask-the-community-7/why-it-doesn-t-align-in-the-center-properly-9206
• https://forum.figma.com/ask-the-community-7/perfectly-centering-22683

Having ("Preferences" > "Snap to pixel grid") enabled by default can cause issues for beginners.

Having it enable can be useful too. So, in order to have “Center a shape with perfect precision.” and “Freely move a shape.” we shouldn’t lose the ("Preferences" > "Snap to pixel grid") feature.

I think the best solution would be to implement this feature, so all of these needs and issues can be resolved.

Let’s say a new option is added for this, as a result:

• (“Position” > “Align horizontal centers”) button will horizontally center the shape with perfect precision no matter what.
• (“Position” > “Align vertical centers”) button will vertically center the shape with perfect precision no matter what.
• Using the mouse pointer, I can freely move a shape, while it getting snapped to pixel grid when appropriate.

Maybe the issue here is that, enabling ("Preferences" > "Snap to pixel grid") limits the freedom of movement. So, what if it doesn’t do that, while snapping to pixel grid?

Allowing to snap to 0.5 and 0.25 pixel (when pixel grid is shown) could solve some of the issues like: https://forum.figma.com/ask-the-community-7/perfectly-centering-22683

Thanks.
