The one thing that bothers me most about using XD--and it bothers me every time it happens--and it happens dozens of times per XD session--is when you go into Text mode by typing T, and then you click on the artboard and type in your text, and then you go to select another object but--and I've never gotten used to this because literally no other design tool does this by default--instead of selecting the object, it creates a new empty text box. All other design tools that I've used (Sketh, Figma, InVision Studio, Principle) switch back to Select mode when you click out of a text box in edit mode. Figma allows you to turn this off--or rather turn "Keep tool selected after use" on--but it's not selected by default.

Honestly, this is one of the main reasons it hurts to use XD and why I am leaning towards other design tools right now and as I build up my design team. Call me picky, but it's just so bothersome. I wish it weren't. Maybe this is how Photoshop works and so you want to keep it consistent for Adobe projects. Fine. But can you pleeeeeeease make this a preference we can turn off?

I was excited to hear that the June 2018 update included Math Calculations which I what I upvoted. I was surprised you said it was completed but I felt like it's not there yet.

So here's my problem that I still ran into many times.

I have a responsive website project with more than 100 artboards. If I change the footer height size by -40px, that means I would have to go to each artboard to manually change the height size of the artboard by -40px as well.

I thought I could select all 100 artboards of different height size and go to the property panel and type in -40px so that it'll update all of them instantly.

But found that the limitation has to be that if the selected artboards shared the same height size, it can be edited.

Here I made a gif of what I would do with the math calculations for multiple artboards of different sizes, except it didn't work :(

Ability to automatically sync document colours + character styles without manually having to click the plus icon.

Problem:
Unless you remember to constantly update these the document can quickly lead to inconsistencies between what is on the screen and what is in the assets. The more screens and the bigger the project the harder this is to manage and reference what you have used in other places, which is critical for digital design.

Solution:
If a new colour or font was added to a screen it would appear under assets automatically. If it was deleted from the screen it would be deleted from assets. This would allow you reference what you are using over multiple screens instantly and would save you having to manually update them all the time.

I can appreciate there might be times where people are working with specific color swatch libraries that are not being used and need to be separate to what is on screen so maybe this could be an option you could toggle on and off.

Please make it possible to add a drop shadow to grouped elements. I have this row with 5 white boxes where each box have a 1 px border. I grouped all boxes to add a drop shadow to the shape as its going to act as drop down menu, but it's not possible cause there are no shadow available in the properties panel. The only way to make the shadow properties appear is to double click one of the rows in my group, I'm then able to add shadow to that single element, but that's not what I want. I want the shadow to be applied to the whole list as one element. I have numerous situations where I need this!
