I downloaded and tested the demo version of ActionOutline 2.0 today. As Steve says:
You can control it without a mouse which is much faster than pointing and clicking all the time. Plenty of clever and intuitive keyboard shortcuts make it easy to manage the information using hierarchical tree structure. The search engine is efficient and knows Polish language which is essential for me. Good product.It's brainlessly easy to use, takes only minutes to learn, and it allows you to create nested outline structures for managing information, including text, images, URLs, etc.
Steve, thanks for information about it.
