Have a Convert Point Tool (To Edit Your Paths)
It would be very helpful to have a Convert Point Tool (I believe it's called) where you can edit all of your paths that you created with the actual Pen Tool itself. I know XD is supposed to be much more simple than Illustrator is, but there are some things that a person just needs to learn before he gets into a design and this is one of them. Honestly, the only reason I switched from Ai to Xd is that the overall work experience is a lot better but not having features like this one annoys me very much.
You can already convert an anchor point on a path in XD, from straight to curved, or curved to straight. To do so while drawing a new path with the Pen tool, simply double-click on the last point you created. To convert a point on a path you’ve already created, double-click on the path you want to edit with the Select tool, then double-click on any point on the path to convert it.
