There have been a couple of recent additions to Blutility/editor scripting that you might be interested in hearing about. They wont hit until at least 4.20, but just as a heads-up.
- Blutilities can now be run via the right-click menu in the content browser (for asset-related scripts) or via the right-click menu in the level editor (for actor-related scripts).
- Additional libraries for asset-related actions are coming on-line and will be developed on a case-by-case basis.
