Stacks Feature for Illustrator, InDesign, and Photoshop
I love using the "stacks" feature in Adobe XD to help maintain consistent spacing between text blocks and objects. This feature is also available in programs like Wix Studio (website builder). I realize that this is mainly a feature targeted at digital platforms where text formatting isn't as robust. However, it would be a nice addition to InDesign, Photoshop, and especially Illustrator for better alignment/spacing control. And yes, I realize that there are other features built into those programs that are meant to do the same thing (ie, align objects panel), but this could be another way of working within the programs.
