Support to import a video or animated GIFs to simulate animations or even playable video.

Global rulers for the x/y axis.

Link a button that can link like a hyperlink to another web page like youtube or my own Web Page

I remember, I have seen this presentation at Adobe MAX 2015. Where we can use dummy / Sample data for content such as Name, city, country etc (Please also think to add lorem ipsum dummy paragraph if possible).

I would love to know, is there any plan to integrate that concept in near future. Its a really great functionality and time consuming important feature for us.

Option to link objects (or generate smart objects) when pasted from a PSD or AI source to maintain a reference.

This would provide a simple method for single or multiple object updates (beyond the CC Design Libraries integration)—saving time and ensuring all objects are the most current.

Example: Revision to a microphone icon via Illustrator, which is used across 20 artboards

It would be great if AdobeXD could provide sort of a library of UIElements from iOS, OSX, Android and Windows besides the given UIKits. So you can simply drag e.g. the textfield to your artboard and adjust this afterwards. This would make the process of designing an app much more easier!

I'd like to have bullet point support in my area text.

To speed workflow it would be good to have button tool in the sidebar. In the property inspector you'd have the ability to specify the top,bottom, left and right padding. the width of button would dynamically resize as you type the button's label.

Make the editable text area's fully justifiable to mirror publication materials.

Ability to create interactive relationships, like radio inputs, if you select one it deselects the other. Selecting different options can change the outcome when the user hits 'Submit' etc

When you choose font for text, would be good to have some preview about how it'll look.

Rectangles: allow 1 or more sides to have a border(stroke), like: border-top

Add unique CSS properties to object properties.
Things like Margins, Padding and un-even borders are not common for design apps, but it would be great to define them per object in XD, honor them in the design mode, and export them as part of the object css,

Ability to align text to the top/middle/bottom of the text box. I'm sure you've already got the horizontal alignment options covered in your checklist.

I would like to use icon libraries (web fonts) without to install them as fonts in my system. For that it would be great to have the option to use all icons of a downloaded "woff-file" i.e. from the following sites and embed them into the xd project:

materialdesignicons.com
flaticon.com
Google Web Fonts
FontAwesome

The ability to add your own UI Kits to the start screen

It's great having iOs etc on there but for professionals working on lots of projects (web based) for big brands there is definitely a need to have custom UI Kits for each brand. This will speed up projects massively as well as maintaining consistency across all projects. Thats essential when you are working to strict brand guidelines.

Make it happen Adobe ;)

One of the main reasons we use Sketch is because of the infinite canvas. For large web projects, there can easily be 60+ artboards at 1920px width, which would run into the edge of XD's canvas. Please make it infinite - it's also very annoying trying to zoom into an artboard at the edge of the canvas, since you can't center the artboard in the view properly.

It would be great to have a generic "find and replace" inside the edit menu like most text editors have. What would be even better is if you could select the find and replace function to use the current art board, or all art boards. This is super helpful if you're mocking up redundant content that has a slight name change between screens.
