I would not choose to add complexity just to change a behavior which, while confusing, is not technically broken.
true, true.. good hint with the sky file. it is just very handy how one can pick a preset quickly without browsing for files (they could be in very different places)
thinking about it from a user perspective, sky files could be in the db manager too.. just drag and drop onto the tab or the viewport could enable them. guess that would make more sense than accessing them in a preset style drop-down menu from the tab where they are stored for convenience (which would be another suggestion)
let me say here, that the db manager is a really great invention, and i still hope that it will at some point become a standalone management system for maxwell materials/scenes like the material editor is. (with a bit more parametric parent-child control of materials and their sub-components)
