Unbelievable how Adobe can render their software more and more miserable over decades and finally totally ruin it. This Acrobat Kindergarten Thing is utterly unusable. Not that this wasn't to be expected:

Acrobat DC SO HORRIBLE it's making me want to cry:

The latest incarnation, in addition to the completely unusable user interface, is so unbearably slow that Adobe can just throw the whole mess in the trash and start completely over. This is the worst and lamest bloatware I have ever witnessed.
