I upgraded to OS3.9 (remembering how nice it was on my A4000T 060/Picasso) but it is disgustingly horrible on my A1200.
IS there a way i can go back to 3.1 without having to reinstall from scratch ?
Remove the unwanted stuff. Take out Amidock and install ToolsDaemon, skip all romupdates and use blizzkick to just load the updated modules you want (scsi.device, FastFileSystem, filesystem.resource, OS3.9 workbench.library, optimized icon.library). Delete Reaction prefs and install 3.1 ones as these are less buggy and if your system "breaks" you can open prefs without having Reaction installed.
Anyway I don't get why many amigans use all available space and just have one boot partition, it's better to have various partitions and space to create new ones.
