With TM2 nice and stable at release candidate 23, and with a major feature of TM being bundles of user-built snippets and commands, it would be much appreciated to have a UI for editing bundles.

Just supporting 1. Drag snippets between existing folders and 2. Right click “create new folder”

Alongside the existing make new, copy UUID and show in Finder features these two would be a major advance in usability.

Even if it was restricted to user-managed bundles (if the concern is to much product support from breaking updates to centrally managed bundles in the first instance).
