- Our assumption on color mapping is that red gets more attentions.
Therefore the color mapping can be changed depending on user's interest.
For example, if a user is interested in the files currently being edited,
red files are new and old files are blue. On the other hand, if a user is
interested in old files so he/she could perform file deletion easily,
then new files are blue and old files are red.
- Early implementations removed
Webview when a content node was selected.
- Several different algorithms are used when variable sized
thumbs are employed. The thumb size may be based on the number of
characters visible or on the number of lines. If characters are used,
thumb size must be recalculated as each line is changed in the display.
For our purposes, we found the thumb based on lines more appropriate than

- It should be noted that unlike most viewers,
the vertical scrollbar to the left of the display window. This was done in recognition
of the fact that inter- and intra-document navigation to find a particular
condition in a document
involved a lot on alternating navigation between and within documents before
an area of interest
was found. By co-locating the scroll bar and its associated Landmark panels
with the interdocument
directory bar, it was possible to minimize mouse travel distance and thus
reduce target acquisition time in accord with Fitt's law.
- It is important to note that the editors also had
available a tool to generate a report of all new comments. The
report, which could be generated in under a second for the 20 or so
documents would consist of any level of detail the editor wanted. In
addition, the report contained links to the comments and to their locations
within the parent document. At the same time, the report feels somewhat
disembodied and the mural scanning approach gives the editor a sense of the
comments in situ along with a view of all the other comments not included in

CASCADE are considered to be comments or observations on the current
