Comments from @mashehu :

• Do we want to add grouping in the user interface at this stage, to avoid having a long list of options?
  • It's already grouped in the code.
• Didn't see the GPU thing in the list? Features list?
• All toggles are off, they should be on, also for nf-core (or decide what the default values should be)
  • Shouldn't be everything off by default, only gpu

Tests are fixed! 🥳
It would be good if someone else reviews it, since both @ningyuxin1999 and me made changes. Thanks!
