Equipment Bond for Software?

[Anaraxes]

For the true minimalist, the Equipment Bond might represent the fact that the character's most effective way of working happens to match the tool, rather than the other way around. It may not be a matter of altering the tool to suit you so much as finding the tool that already works the way you work best. There's more than one minimalist editor, after all.

It's okay if other people could have a Bond with exactly the same tool. That just means it suits them, too. Bonded stuff doesn't have to be unique in the universe, nor does the Bond itself have to be unique, so that no one else in the universe could Bond with a copy of that item.
