Always Be Saving

[nickzoic]

Working on datasets in Countess I find myself adding "Save CSV" plugins scattered all over the place, to store intermediate results, which obscures the flow of data quite a lot.

For example, compare these:

Before	After

Maybe it'd be more sensible to have an automatic "Save As" at the bottom of every node to reduce clutter?

Plus (maybe) saving intermediate results would be an efficient way to handle regeneration of data?
