Apex Unified Logging 
Logging framework based on Salesfore Platform Events to overcome the limitations of System.debug logging.
TL;DR - Show me a video demo!
Features:
- Provides unified view of logs over transaction boundaries (a.k.a. execution contexts)
- Groups Logs of the same Batch
- UI only shows the logs produced by current user
- Autodetection of Code Location
- Nice UI using a Lightning Utility Bar
- Activated using user-level custom settings
- Easily extendible to report exceptions and Governor Limit state
