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

OMG thank you so much to that person above who said to hold down the shift key for transform.  This has been driving me insane since the new version was launched and I've almost put my fist through the screen a few times!!!  Please Adobe, revert back to users choosing when to lock and unlock the transform cause I was hitting that lock symbol and it wasn't working at all!  Thanks again above folks, my sanity has been saved because of your comment. ❤️ 

Right, I think the keyword is "BUTTON". No deep programming, just the ability to lock the "maintain aspect ratio" button which works then for everything and can temporary reversed with Shift (in whichever state it was locked).

A simple "Maintain aspect ratio as default"-button would've done it. You know, to keep that little link button on by default. So easy, yet you managed to make it all way too complicated somehow. 

Dear Adobe,
Please fire EVERYONE involved in the Transform tool screw up & revert it to it's familiar behaviour. P.S. I also use Affinity Photo & I'm close to ditching Photoshop because of idiotic changes such as this.

It's really not very obvious. On the right across from your version of CC2019 in the Creative Cloud app's Apps section, click on the disclosure triangle next to Open (or Update), and choose manage. You don't need to uninstall 2019 to install 2018 (though you can if you like). But that's where you can both choose to uninstall AND choose Other Versions, where you can reinstall 2018.

At least you are not completely on dark side 😉

Use Adobe Creative Cloud application. There you can (un)instal certain version.

Besides it doesn't matter for this topic, I'm sure you are normally scaling things to fit the size of other things. Imagine composing people or trees in a background... and they need to maintain aspect ratio. But this diskussion is not about which default is better, it is about to make it easy on-the-fly customizable for whatever workflow the user needs for his indiviual tasks.

How do you uninstall CC2019 and revert to CC 2018?

Now in  Transform holding option constrains the aspect ratio, Who the heck decided to change this convention?? It's nuts and against everything we've learned. PLEASE REVERT to SHIFT constrains. PLEASE!!!!!!
