This is just a small thing but would it would be useful to open other 3d files (e.g. .obj) in blender and have it automatically import them as opposed to the "The file is not a blend file" error. Would their be anyway to have it automatically search the import scripts to find the script for it or even to give you the option of importing the file and you select the script?

For architectural visualizations I think it would be useful to be able to record the camera's fly by mode. This would be a lot easier than setting up curves which can get tricky and stopping the flyby every couple of frames to set a keyframe is not as smooth.
