Here's a few ones that would make my life easier (in no particular order):
1. Zoom to 1:1 with Crop Overlay Tool
2. Search for keyword's synonyms
3. Dodge & Burn
4. Local contrast enhancement
5. Split (and merge) libraries
6. Conform to keyword capitalization when suggesting keywords
7. Bring PKS and Noiseware into LR without the round trip to PS
8. Generate an optional log file of the import sessions
