It is easy to use and very helpful. I just started so I am a bit slow in getting the documents made or using it. I would have liked it a bit more straightforward, but I like it so far.
Francesca
All good. However it would be nice to be able to move the type up and down when placed on the page rather than have to keep placing the type symbol in a spot where you think it will fit on the line.
Janet M
Pretty easy to use! Pretty easy to use!Update: Been using this a while now, only down side is that when you blank off certain information, save the file and open it to check, for a very brief second all the old information flashes up.
