"The clean layout and fairly simple questions work well for users with simple returns, however a few UI tweaks could be beneficial.
When walking through questions, there should most likely be some sort of tree showing the user where they are in the process. I seem to recall this being done better in last year’s version.
Some of the walkthrough questions automatically add forms, even if the forms do not apply. There were some sections I should have skipped, but did not just so I could clear the little 'not visited' text from the section summary. Even though some of these did not apply, one or two did not have an introductory question checking for applicability and added forms which I had to manually delete out at the end (the error checker did throw flags for these forms - to its credit)."
