Nothing Particular other than finding out the particular IRS forms I expected to print from the IRS wasn't acceptable to download and print, and I had to purchase them when you advertise free IRS forms.

So far great! Just wish we had more options on auto-page numbering. If your document has a cover or a forward like a book, those are pages you don't want numbers on.

Easy to use. Lots of Features. Need to pay a few more dollars to use everything, but great value if you need to combine different documents to create one.

I wish there were more typfaces I could use. Also, I couldn't figure out how to italicize titles within the document without it italicizing all around it. I gave up after several attempts. Wish that part were more user friendly.

THE BEST support team I have ever had, EVER!!!!!!!
Best support team I have ever had. I used the dreaded "CHAT" where I usually end up banging my head against the wall. Today I chatted with Sam and I am dumbfounded how great things went! I can honestly say I have NEVER had the satisfaction that I got today! I can't even think of a chat before where I felt human afterwards. Today, I am gobsmacked how well everything went!Sam took care of what I was there for and did it with professionalism like I have NEVER experienced in a chat with a business!I can not say enough about this company! If Sam is an example of the company, which he is, then this is a 10 star company on a 4 star scale!

Work and Study Budy
Overall I love the app and all the features it offer! The benefits totally outweigh the cost. Amazing app!
What I like most about the feature is I can use it both for work to fill out pdf files and for my personal studies where I can write notes, comment, add highlights and more to the file.
What I least like about this is it can be a bit pricey to maintain especially if I were only a student. But good thing I am also using it for work so I can really maximize its use.
