The naming rules for many files and file paths are very strict, and changes or versions or numbers are always the last part of the name.
So we often either can’t read (and identify) the most important last part of the layer name or we need to waste a lot space on the monitors.
And properly working on a laptop with more than one layer visible is often impossible.
I attached a rough idea, what option Photoshop should get to display names.
Especially in documents with a few hundred layers became just normal this would be a important update.
