The capacity to swiftly and seamlessly combine document elements and repurpose content is very nice. Help & Manual is an affordable product that is simple for beginners.

The ability to reuse the material and recompose the document by merging the parts simply and quickly

Both reliable (crash-proof) and intuitive. I have been working in outline form since college and this program pulls together massive help file and documentation projects with ease. Being able to write it once and use a few compile directives to hid things that are not needed in say a PDF manual make publishing simple and fast. Reliability is important to me because crashed programs are frustrating. I have never lost work in this product in 15 years. I can't recall locking it up or being stuck either. Confidence follows.
