Column Widths on the Details Pane when reviewing differences appear to be fixed and not changeable (all I could manage to do when trying to re-size was to sort). As a result, it's not possible to see the differences in many cases when the displayed part of a particular property is the same on both sides.
An option to ignore differences for future comparisons would be useful: For example, I compare two packages on two servers (say Dev & Test). The only differences are the server names for example. I wish to therefore mark the data-source property for each connection as ignore for comparisons. Then, next time I compare, if anything else has changed, the packages show as different, but otherwise they appear identical.
Smart Comparison would be really good here - an option to repace instances of the server name with a token on both sides of the comparison, so that differences that are due to the fact that the package is on a different server only are hidden.
For example, for a standard SQL Server connection, the DataSource for local database tables will usually (at least in our shop) be the server name. If DTS Compare (logically) replaced it with say (local) on both sides, then the two connections would appear to be the same. I should point out that we deliberately specify the server name rather than specify (local) so that we can develop the packages on our dev PCs rather than the server. Similarly, we tend to use UNC names for both files that are data sources or targets, and for logging locations - for the same reason. We would specify a source as \\MACHINENAME\SHARE\DATASOURCE.TXT. If DTS compare replaced \\MACHINENAME\ with a token, again these items would compare as identical.
