I'm not sure I understand the third question. Are you talking about an inline or anchored frame inside the running text?
In any case, the answer is basically that there are no changes at this time since version 3 that would make your life any easier with regard to paragraph borders, highlighting, or splitting anchored frames or table cells.
Thnaks for your reply.
Yes, I'm talking about an inline frame. Would be nice if that could split over column breaks.
I found a plugin that would cater for points 1 and 2:
Interesting plugin. Will it split the vertical rule or highlight across columns? The description doesn't mention that.
And who's this Phil fellow?
Oops, Sorry Peter! ;-)
I've just downloaded the trial and it seems to do everything I want including spanning across column breaks.
