Thanks to Bernard and Darren for your comments.
I agree it'd be nice to see more type-specific icons. We're to some extent constrained by how much the DTS object model reports to us about each type. We could fudge it for folders at certain positions in the hierarchy, but that wouldn't be as "nice"...
Priority wise, setting your DTS Package Compare process priority to low is definitely a rather handy way to give priority to your other applications. I can't see that any nasty side effects would occur, so depending on your setup this could be a generally good solution.
We're not planning for DTS Package Compare to default its own process
priority to anything other than "Normal"; however our worker threads will have their thread
priority set appropriately. From Win2k onwards Windows' scheduling is such that thread priorities don't mean as much as they used to though.
Re filtering, I'd might suggest trying setting Connection2's "Connection Properties" property to "Show but do not compare". If I understand which data source property you mean, this should prevent data source names from being compared.
Thanks and all the best,
