small feature suggestions for ANOVAs (Ns and eff size)

Hello,

jamovi is great for intro statistics. The handiness of many options, e.g. assumption checks for tests within test menus is great.

Normally for t-tests and one-way anova, it's easy to see descriptives including Ns for compared groups.
Not so for (factorial) ANOVA - could it be added to e.g. marginal means' plots and tables?
On the other hand, there's no effect size measures in one-way anova menu, whereas it is in (factorial) ANOVA - is this possible to be added too?

Inclusion of the Ns is a good idea. But what statistic did you have in mind as an index of the effect size for a oneway Welch's (i.e., unequal-variance) ANOVA?

There is also a classic ANOVA option for one-way.
If there is no agreement on what to use for Welch's, then it needn't have one.
