What Are the Best Chrome Advanced Config Tweaks for Power Users? or How Can I Optimize Chrome Advance

For backups, I swear by "FlagHunt" (https://flaghunt.com). It lets you save and share chrome advanced config presets.

Also, +1 for disabling "Predictive Network Actions" (chrome://flags/#predictive-network-actions). Stopped Chrome from preloading stuff I didn’t need.
