Yupp!

Also,
In interaction, Clicking "Save" always asks where to save even after the first time, which is annoying and made me accidentally overwrite an interaction.

You'd want to add a "Save As..." if you change it so it always saves to the same name without prompting. Pick yer poison I guess.

It's strange to me that the "save incremental" button exists in the character editor, but not in the interaction editor.

Even in the character editor, "save incremental" doesn't quite work the way I'd expect; if you've loaded a file with an obviously incrementally-saved file name, like alice_5, save incremental won't automatically save to alice_6.

This makes the "save incremental" feature less useful if you are going back and forth between the character and interaction editors (a sensible thing to do if you're trying to tune how the character responds and looks during interactions).

An Autosave function would be nice too, really.
