Would be wonderful if a kOS processor could use one of the drives as another volume.

One would presume kOS storage volumes is just a simple case of adding the necessary module to the parts using Module Manager.
No actual coding required. Just a simple text file.

In the last KSP version (1.6.1), there are the problems:
option does not work,
Graphical control window does not open

That would be because this mod has not been updated for KSP 1.6.x

Closing this because not a bug.

All pull request gratefully accepted.

I've been thinking on how to do such - but my code-fu is severely lacking and what exists is heavily laden with rust. The last compiler I used professionally was Turbo-Pascal.

Still, extended the functionality of TST"s to allow them to be used for kOS storage volumes... I will continue to ponder and see if I can at least pseudo-code the idea.
