Dynamic size and styling properties
It would save a lot of time is I could set the size and color properties of an element dynamically.
Usecase: In my prototype I have a canvas, with a tab-bar on top and two side-panes, one on the left the other on the right.
I don't want the panes to overlap the canvas or the tabbar, so I need to shrink/grow my canvas and move it to a new position when a pane is opened or closed.
This could be super easy if I could set the value of the x position and width of my canvas and tab-bar properties via a variable. I would then (re)calculate the variables whenever I opened or closed any of the panes.
I have to recalculate the position and size for each element that I want to move (or resize) individually whenever I open or close a pane.
Another benefit of using a variable to set the position and size in an element is that I could see in the properties that the value is a variable rather than fixed.
I have the same issue with dynamic setting of a color. I use color coding in my prototype and want multiple elements to change color depending on the zone I'm in.
