Ditto! You've summarized this entire thread that has been going on for several years. I think no corporate ear has the responsibility or interest to hear this complaint. A couple of years ago, I went to OneCommander, and it works well as an alternative. Of course, I've had to "learn" the new idiosyncracies of Explorer, which change occasionally without warning and without apparent purpose.
The older someone becomes, the more important this type of issue becomes. Younger professionals, such as the ones in charge of making these changes, surely think they have a good idea that will help. However, they are unfamiliar with long-term familiarity and its interaction with productivity.
So we spend money on new settings, layouts, functions, conflicts, etc., and then enjoy the benefits of a new look.
C'est la vie! I might say, tongue in cheek, "Only in America, Land of Opportunity."
