Usability issue in Tree vs Node for ops that have children

[IanMayo]

IMHO we have an issue with how we display the subtract operation.

Here we have it with two numbers selected:

And here with three numbers selected:

In my opinion it's right to show "Subtract" as a tree/folder - whether there are applicable child operations, or not. It should be consistent across the two.

Hmm, maybe not the same folder as for "Sublibrary sample". That folder is clearly for organising child operations. I can work with my designer to come up with a new tree icon for an operation that contains children. Temporarily, could you use another standard Eclipse icon for these "Operations with permutations" objects?

The standard Eclipse project icon was used for non-commutative operations, while the Eclipse folder icon remained for the libraries & sublibraries:

Even without children same icon is used (disabled here):

Those icons look great, thanks.
