My only response to a comment like that would be to tell you to stop using it. I use Lightroom Classic, and enjoy using it. I have very few problems with it, it does what I expect it to do. My computer is old and slow. But then, so am I. If you would care to share what your problem is then perhaps we could Provide assistance. But we need to know the exact version of Lightroom you are using, what operating system you are using and a little bit of information about your computer system.
Please explain what it is exactly that you "HATE" about Lightroom.
