Keeping my tool preference
Since Adobe's CC platform, I actually dread major updates because they seem to wipe my user preferences forgetting all my shortcuts and forcing me behavioural changes each and single updates.
The latest was the disappearance of Illustrator knife tool from my tool set. Little did I know that the knife tool is under advanced tool section, and that I needed to switch to my tool to advanced mode in order to use the knife tool. There may have been other nifty Adobe ways to access it, but I just simply don't have time to relearn all that stuff.
Adobe, let's imagine this in our analogue world,
I as a practicing artist / tenant often fighting and trying to meet client deadlines, one day walk into my studio and notice all my setup (brushes, canvas, paints etc arrangements) had been rearranged by you, the studio landlord. You broke into my studio and did all that like some heartless landlords might do these days even though I pay my rent in full and on time each month. Perhaps because you fancied your studio building renovation so you can jack up the rent for new comers.
I hope you can understand how annoying this is to me? The least you can do is to leave my stuff alone and keep my user preference in tact. To be honest I think you are asking for users' behavioural changes way too often with your products.
