Features wanted: Delete unused components / Navigator

Hello, I have been using XD for about a year now for UX prototypes and though I'm not sure this is where ideas for the program are being pitched I felt like leaving these two in here as they will be read anyway.

I'd like to see the folliowing in future XD releases:

* Delete unused components — If any given component registers no instances used on canvas, have the option to delete it and thus reduce asset clutter.

* Navigator — This is a big one for me. I tend to work with dozens of artboards per document and all that scrolling eventually gets tiresome. I envision something akin to navigators found in Photoshop / Illustrator.

* Prototype View: Better destination handling — Again when you have dozens of artboards per document trying to find the one you want to point to in that tiny select box is really trying, even if you're careful with naming. There's huge room for improvement here. An acceptable alternative to this would be the ability to link separate XD files together with the ability to share assets across them. so as not to need to build a single humongous file with dozens of artboards.
