Sure, I've made a note and we'll try to get to it soon after the 4.0 release.
The trim dialog seems to remember the last setting used, but there doesn't appear to be a way to get the trim settings. The best we could do it reset it to check all of top/left/bottom/right.
Actually we found a way to avoid using trim at all, and it makes the script faster, too! :greatsuccess:
