This is a post that is on Reddit and a few other places as well.
Months ago I told several members that I was working on an Add-In that gives advanced functionality on editing points. We're talking things like:
* Move multiple points at the same time
* Move points with your arrow keys
* Make the point icons invisible so you can clearly see the line you are adjusting
* Move multiple points on multiple shapes at the same
* And so so so much more.

Here is the first Dev Vlog on the Add-In.

This particular Add-In will be free when it's released because PowerPoint should already have similar functionality like Inkscape, Illustrator and several other vector editing programs.

Please have a look at my video introducing it and give some feedback on what you think it needs, doesn't need or any suggestions at all.

Thank you all so much I hope to have this all done soon for you.

PS: I am an animator and voice actor for my cartoons so yeah you have to deal with my quirkiness.
