This is a properties notebook which allows you to select which part you want to use for each registered data type. Thus whenever you open a document on your machine you always know what parts will be used for each kind of data, be it text, tables, 2D graphics, images or whatever. The OpenDoc 1.0 that ships with Warp 4 is certainly not nimble on its feet without a lot of memory and CPU power. Scrolling speed in the Page Layout container was slow and the lag-time when typing in the Text part would occasionally slow to half a second between letters. There was a considerable amount of unnecessary repainting going on when changing window or part focus, making the page flicker.
Integration is superb, however.
Not only can parts be edited in place within a document as well as on their own, but the whole OpenDoc kit feels like a real part of the Workplace Shell. Properties notebooks look just the same as regular WPS notebooks, complete with 'File' and 'Icon' tabs. Support OpenDoc's success hinges on good third party support. The ability to pick and choose your editor doesn't matter much if, as we pointed out, there is never more than one editor for each type of data. But at this time things aren't looking too bad.
