external externsion

[Hank]

Would it be possible to change 'make external' logic for texture in outliner area?
When the UV map is ready and texture created, I go to Outliner window, RMB on my new texture and choose: make external. There are several extension types [by default .bmp] but when I choose any other, the file extension is not following my operation [still stays .bmp]. Conclusion: it doesn't matter that you've chosen other than .bmp extension, you still have to put proper extension for the file [system will not allow to keep the file without extension]
In other words: If I select .png extension, then new file name should follow it.
See my recording for proof.
