Master page feature will be very useful, in Adobe Fireworks master page feature is good example.

Also option to share layer (group of layers) to multiple art-boards will be very useful.

For example you are using cart widget on several art-boards, and ability to share same layer (cart widget) on all of them (including positioning top-left from art-board) will save lot of time when editing. This is not same as symbols because here you share also positioning of layers. In ideal situation you create symbol "cart widget" place on art-board, position where you like to appear, and than share that layer across multiple art-boards. Latter on when you need to change/adjust position you can do that from one place.

Yes, we really need this...

Yes, it I similar to the suggestion on master art boards. It makes sense to merge the two ideas.

And changes to the artboard should be reflected in the symbol. That way you would have the same functionality as Master elements in Axure RP.

It would be useful if you could turn a complete artboard into a Symbol. It would make it much easier to add new elements to a symbol.

This could be implemented by simply allowing to select another Artboard as the current one's background, instead of or additionally to a fill color/gradient (in Appearance section).

XD needs master pages, like in InDesign, but I imagine it a little simpler here. In InDesign, a page is either a master or a regular page, and they're stored separately. You have to turn a page into a master page, which I'd hope you don't have to do in XD. In XD, it would be great if any artboard could simply apply another page as its underlying image. You could manage it from a dropdown right by the artboard name-- something like, "Based on Page xyz". And then, if you're zoomed out far enough, maybe when you roll over that control, it might highlight the master page with a thick border, and any other pages based on it with a thinner border of the same color. A control to "Jump to Master" would help you easily find it in your sea of artboards when you need to make edits to the underlaying layer.

I have the same button on many artboards, and would love to reposition all of them at once by selecting them all, then typing in the X-Y coordinates in the info panel. Doing each one at a time is a pain!

When updating a universal symbol like a logo placed on the header. If it's X/Y changed from 60px to 100px I want to apply this new coordinate universally across all boards when 'update all symbols' is selected.

I did a test today but 'update all symbols' option didn't update new position.

Yes! this feature would be very helpful!
Any progress on this?

This would solve a lot of pain that is keeping our team from total adoption.

Looking for feature to define Universal header and footer for mobile app prototype. Once design define fixed header or footer and may be both at same time and middle area of app would be scrollable.

why isn't this standard? seems so stupid

I'm still waiting on this pin objects feature, it's coming up to a year since I added a comment on this post...I've been unable to use Abode XD for my work as I feel pinning objects is a must. I wonder why this hasn't been addressed yet :- /

It would be great if it was like indesign master pages!

For example:
If i created an textbox in Artboard 1 which says "Home" and i've got an copy (or more) of Artboard 1 with the same Interface and the "Home" text, it would be easier to link the textbox in Artboard 1 with the textbox in Artboard 2. So if i need to change the text, i only need to edit one of them to change both.

And (it would be nice to have a choice activating this option) if i move the linked content in Artboard 1 to another position, the position in Artboard 2 changes also.

I would like to see one masterboard, where an edit is made to any object (that is copied to other artboards) then the copies boards automatically update based on the masterboard - this should be optional, suggest when creating first artboard to indicate whether it should be a master board or not.

yes, smart symbols I think is better than master artboard. you could select a symbol and then pick either "show on all" or "show on selected" artboards.

I would like to animate to different views while keeping my header/navigation in place. Right now it appears that all XD will do is switch to a whole new view, which feels very unnatural.

Object / symbol can be moved on all artboards at one go, reflecting across all artboards. Same coordinates across to speed up the changes. Could be done pressing a key with mouse to move across all artboards or without key combination to change individually.
