P: Free Transform - ability to set Maintain Aspect Ratio as default

this new update is driving me absolutely insane. 10min to figure out how to figure out how to revert to the old undo system, draw for 2 min, 15min to google why my brush is lagging, turn off ruler and draw for 5 min, 30min trying to figure out what the hell happened to the transform function. How many more more surprises are gonna trip me up? I've never had to actually look at the updated features to preform basic functions in PS. I do NOT want to have to relearn the program every time you decide to roll out an update. 😕😕 I'm trying to get things done and it's set me back at least an hour by this point. I am so close to reverting back to the 2018 version, I don't want to learn new habits only for you to change the settings again. 

Come on Adobe! Do you actually have UX designers and QA? Because is just unacceptable...
People are used to the old behavior and the new one is just completely broken. The toggle "lock" button doesn't even work! The behavior is very inconsistent across Adobe products and even in Photoshop itself. Revert this and go back to the drawing board, if you think this is actually an issue. I'm sure there are better solutions.

Stupid move sorry, on so many levels.

This is seriously screwed up.  I think there's a memory issue.  After using Photoshop for awhile, free transform no longer works, even if you unclick the chain icon.  It works for awhile if I restart Photoshop, but eventually stops working.  I have 64 Gb of RAM and never had a problem with the older version of Photoshop.  

This version is pretty much unusable for me, unless I want to keep restarting Photoshop, which is a pain if I have several images open at once.

Marking this as "Implemented" is an insult. What was implemented was nothing like the above request, but a slipshod afterthought that nobody asked for. A muscle-memory challenging, workflow-interrupting, inconsistent and clumsy UX disaster. 

And give us more room to rotate without accidentally committing!

yeah, it's kind of a big, giant trainwreck.

Jeff, just a heads-up that transform/distort now requires the shift key to properly distort. I imagine that for 99% of the users, contrstrain distort is not what's wanted when invoking distort.

it just doesn't make any sense - the only place this should have been a default behavior - is when you grab a CORNER.  If i grab a side transform point... why would I want the other sides to scale too!
