Math Calculations for Multiple Artboards of different sizes
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 :(

Similar use case. Import a push of Hi res images, I want to change all the images to 0.5x. I currently have to select each and and type /2 "enter" in the height or width box.
I'd like to select multiple images of different sizes and enter "/2" into the height or width box
So in my current situation that I'm facing at the moment, I made a report that I thought would be entirely created and designed by an app developer. But later learnt it'll be a website page inside the app, so have to make some modifications to the design layout.
So here I have more than 20 artboards that need to be resized by adding 44 more pixels to its height, so I could paste the tab bar at the bottom of each page. The problem is I have to go to each page and resize them individually. I wish I could just choose which artboards I want to be selected, and go to the artboard size property panel and hit "+ 44" inside the height input field. And then paste the tab bar and hit "align bottom".
I realised Sketch does this too.
