Lotus Improv, a pioneering spreadsheet application exclusive to the NeXT platform, introduced innovative concepts like multi-dimensional data modeling and English-like formulas that presaged modern pivot tables. Developed during NeXT’s struggle to find market traction, Improv redefined spreadsheet design by emphasizing named categories over traditional row-column references, enabling more intuitive and flexible data views. Despite its failure to gain widespread adoption, its legacy endures in contemporary spreadsheet tools and in NeXTSTEP’s influence on modern operating systems like macOS.
