I would like to change an icon symbolizing change with something more appropriate. Currently the icon is a star. After giving it some thought I realized that I didn't have a good concept of what symbolizes change (differences, not coinage).
I had thought of using arrows, but most designs reminded me of recycling, refreshing, or forward and back.
Edit for clarification:
I'm updating an icon used in a bug-tracking app for "change" tickets. That is, an item that will be changed in some way.
