Easy-to-use program once you fiddle with it awhile. Would like ability to edit text also (portions that are inapplicable rather than striking through).

I have tested it and every elements concerning my line of work are deeply thought out and very crisp.
I had a problem of sending a folder but the solution is in merging the files to create one new file to send.
The software is brilliant and less costly than all the competition I have tested.

I like the program, but I really needed the ability to add Bates Numbering.
If the program would overcome some of the rather important limitations, this would
be an excellent deal for the money.
