Support for simple animation.
Example: Show/hide a slide or push menu

This would enhance a demo and engage prospects that are familar with common application patterns.

Need Little bit tapping/hover effect on list/buttons/links during presentation to client. Its give an actual working product feel and help to make decision.

rollover, mouseover

Define a scrollable area within an artboard

This provides real-world app use cases, such as a table, slideshow, or iOS dropdown lists.

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

An ability to drag out persistent guides to an artboard and have other objects snap to it

Provide the ability to change multiple objects/elements within a document and/or across artboards.

Example: Ability to increase font size within a button across all artboards (without multi-select)
This is similar to increasing font size within a repeatable grid—all increase.

Another example: replace/swap a theme color throughout the document.

Ability to create and customise content carousels or slideshow type scrollable areas.

Currently there is a "scroll" feature in build, but it seems to be about page scroll and up/down scrollable areas.

Add basic text transform like there is in Illustrator to make it easier and faster for developers to code your designs. Our developers have to waist time retyping text for layouts that have already been designed. At least basic uppercase and lowercase.

It would be great to Export Prototypes as pure HTML Projects. I am working a lot on Multiscreen apps, where I mostly use Serveal Webcontainers Running on several Screens, to develop those Applications.

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.

1. Ability to have a single object (or group) break out of its artboard and cross multiple artboards within a single prototype. The simplest use case is the creation of a global navigation bar that spans across multiple screens. This object's interactive elements would also work across multiple screens as well, and any edits to this object would update across the rest of the screens.

2. Easy interaction management and editing. Also provides consistency with consistent elements within an experience.

In order to full use this as a UX professional, I would have to have the ability to include gestures, most critically for handing a stakeholder a wireframe or design. Gestural swipes, two-finger zoom, force-touch, etc. Otherwise I don't think too many experience UX professionals will be able to properly communicate core functionality and the behavioral imperatives incumbent to the process.

This would make it easier to use the assets created in other Adobe applications.

Global rulers for the x/y axis.

Import Illustrator file with options to select layers and/or artboards.

This would increase ease of use and workflow, so a user is not always switching between apps.

The anchor link that target the specific part of the page. This is the significant user experience on web usability where user can "back to top" or can navigate (i.e. from menu bar) to the specific sessions without the need to scroll through entire pages.

The option for a darker interface like Photoshop and Illustrator would be great, especially when working at night.

I love the addition of symbols to XD, only let down (beside the ability to re-organise them which is already posted as an idea) is that I have to create a new symbol for every required size.

Please let us scale the symbols

I am trying to create icons in XD and want to make sure they are symetrical but there is no flip option in the edit menu.

I tried to use the width, height and coordinates to do this but without guides, or the ability to unlock the ratio this does not work either

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
