After a little bit of coding, the 2+ test condition dialogs have been written! I've included screenshots below with the wireframes to allow a comparison with the real thing that's now working.
The code is not yet uploaded to GitHub but needs to be connected to the statistical test code itself. When that's done, Salstat will be able to do within- and between-subjects ANOVA, Kruskal-Wallis, Friedman and Cochrane's Q tests.
