 ## Must
 
- - UI revamp
  - hardened_usercopy=0 page_alloc.shuffle=0
  - add value_profile but only enable after 15 minutes without finds
- - cmplog max len, cmplog max items envs?
+ - cmplog max items env?
  - adapt MOpt to new mutation engine
    - Update afl->pending_not_fuzzed for MOpt
  - cmplog rtn sanity check on fixed length? currently we ignore the length
  - afl-showmap -f support
  - afl-fuzz multicore wrapper script
  - when trimming then perform crash detection
- - problem: either -L0 and/or -p mmopt results in zero new coverage
