Just kegged an IPA made with US-05 which was quite cloudy. Found a thread in the archives describing the process, so I added a little over a tsp of unflavored gelatin bloomed in 8 oz ~170F water and gently stirred it into the keg with a sanitized racking cane. In just 24 hrs it was noticeably clearer and now sparkles like it was filtered (one week later).
If you're bottling, you'll need to fine in primary before transferring to the bottling bucket, but from my experience it's very worth it. Much quicker than just cold-crashing, and leaves nothing behind in the beer.
Don't think it will affect aroma, but not really sure - my dry hopped IPA has a full, pungent, aroma as expected.
