There is some frustrating quirkiness in the way tables work in places. There should be greater control over how the underlying table structure is created, rather than being strictly dictated by the generation process. There is room for improving the way Fusion incorporates scripting within elements, as well as how it relates to external HTML documents. If you don't want to convert an external HTML page into a Fusion page for whatever reason, it can be imported and edited using your own editor. However, what you see on the page is a giant X across the viewing area, rather than what the page actually would look like.
Fusion also is RAM intensive.
More than 20MB is required for a site of 20-30 pages on my PowerMac, though the number of pages doesn't seem to affect the RAM requirement very much. I am experimenting with ways to reduce that overhead, including breaking larger sites into smaller segments. In Summary Just as you would not open a desktop publishing program for the first time and expect to know all there is to know about how it works, don't expect it from Fusion, either. Fusion may not be the panacea in the search for a DTP-style Web design program, but it is powerful and relatively affordable. What is required to fully utilize the program is yet another paradigm shift away from focusing on programming and coding toward a new view of Web work as analogous to electronic publishing.
