Suggestion: From one version to another

[Almazoioio]

Hello, creators of that really usefull site that I was using for a pretty long time. So when I ported one mod from Forge to Fabric and then started porting from 1.16.5 to 1.20.4 I had stumbled across one problem: There is no porting from older version to newer (and the other way around). And now I'm facing a big struggle because I cant look up by net.minecraft.class_XXXXX and IDK the namings of new-version classes (Now my progression almost stopped)

I hope that this feature will be added, thanks for your attention to that problem
