• Automatically formatting code using GitHub Action (as suggested by issue #141); (Easy)
• Sacrificing some compile speed to move most of the magic numbers out of the .cpp files (by using some dark magic, maybe the run-time efficiency can be unaffected); (Normal)
• Adding logs and comments; (Hard)
• Eventually rewriting the whole repository, bumping the version number to 3. (Lunatic)

• Providing some easy-to-use APIs for everyone to customize their specialized training. (Please refer to RUEEE's fork)

I doubt we can finish the above before Comiket 110. (^^;;
