Please return the posibility to "Show layer at all scales" that exists in ArcMap!
This function makes it easy to override and swich between a scale that's set on a layer, and being able to watch the layer at all scales. In ArcGIS Pro now you have to write down the scale on a paper to make sure you don't forget or change it while you look at a layer in any scale and then write/set the prevoius scale again on the layer after checking how it looks.
