Frame Work was one of the early software "integrated suites" (I used it in 1986). What made it intersting was that each document was based on an outline, with each node having potentially a different content type (spreadsheet, db table, text, etc.). So you could show/hide different levels of detail, restructure the document easily, etc. (Another probably-important thing was that it had some fairly-real language built in. But at the time I didn't appreciate that.)
