Hi,
It would be a huge improvement to have the reference keypoint tool, the same as in InDesign. The tool is very useful.

Ability to manually drag an object's anchor point. Sometimes you want to rotate or enlarge objects from a certain location, it is useful to be able to place that anchor point wherever you need it. Just like in Illustrator or InDesign.

+1 When working in development environments with center center origins, this is critical. Thanks so much for this awesome tool! XD is the bomb.

+1 It's a must have. I currently have to spend extra time aligning elements properly because we lack this feature.

+1 This is essential. I don't really see any pro to leave this out, only cons. Lead's to very slow workflows manually re-aligning things by eye instead of using the numerics pad

When changing the size of an item numerically in the dialog box, we know that the ability to constrain proportions is something you're working on — but what I am finding frustrating is not being able to set the anchor point (top left, top center, top right, center left, center, center right, etc) like in the other Adobe apps. Going to the trouble of having to manually re-center elements each time they are resized numerically is time-consuming

In Illustrator you can select the axis upon which an object rotates. When designing metric visualizers and other tools I need dials and other elements to rotate around a specific point. Being able to select this rotation point would be extremely helpful.

Please add the reference point to XD!!! It's fundamental to transform object easily.

+1 for adding a reference point (origin for transformations). A major feature that Sketch overlooked. I use it constantly in Illustrator for manipulating objects, and it'd be really nice to see in XD.

It could very useful when we test different sizes for an object and we dont want to replace it every time.

This make transformations so much easier, please!
