Place I work Is doing an overhall on our app ui right now. They gave us a beta build to play eith as we use the damn thing as well as supported it.
It was shit square buttons down the left side and nothing else which would have been fine if the plan wasn’t make it preview to our customers.
They pulled the preview when we pointed out all the day to day stuff was all behind 1 button meaning out of the whole screen about 90x90 pixels was actually usefull.
The number of times we point out holes in the design is scary and always has the same conversation pattern
