Longer-term plans


Highlight individual words changed in a line
Fish-eye zooming for large files
Requires knowledge of file syntax
... but we want that anyway, to do syntax highlighting
Display changes to entire directories, with file granularity
Use the usual "holophrastic" tree (as seen in Windows Explorer)
nice and simple to implement
may work as well as elaborate cone views (Cockburn)

Per-line annotations might be handy
similar to what "cvs annotate" gives you: author, date, revision
Put them at the far right (if all the change markers are moved to the left)
User control over information in annotations
