- I am a class that should exist, but my features are burried in other places. So, for now, I am just a placeholder comment for a future refactoring. I should be responsible for:
- - Keeping track of which things in a DSChangeSequence are selected, or visible in a UI, kind of like a Tweak costume. This is currently kept track of by the shownChangeIndexes and changeListSelection ivars of DSDeltaStreamBrowser
- - Executing queries on present and incoming changes, and using the results to determine selection status. This is currently split between various menu entry methods in DSDeltaStreamBrowser, and the grouping methods of DSChange
- - I should also, perhaps, take responsibility for presenting a costume for changes in my wrapped change, so that they can be associated with view-specific properties, such as highlight  color, or selected changes if I am a heiarchial change. Some of this is being done by DSUIApplier!
