I don't like that you have to hard return on open spaces or the text goes off the page. I don't like how there is not any guidance on the cursor in pre-developed forms-there should at least be a grid view option. I do like how clean it looks and intuitive it is to use.

I like that I can find most of the forms I need bit it is very difficult, at least for me to align some of my typing to the actual
corresponding lines. (eg): pleading paper. Im sure there is a way but i haven't learned the whole program yet
