Help on Moving Transform could be better

Timeseries version

0.5.1

Orange version

3.33.0

Expected behavior

When clicking the ? in the dialog box of Moving Transform, there should be a clear explanation what to do in order to compute a Cumulative Sum (probably also true for Cumulative Product).

Actual behavior

The explanation does not include instructions on how to compute a cumulative sum. Cumsum only works in the setting "Sliding window", which is not completely intuitive, especially since it looks as if the Window width needs to be specified (in fact, it doesn't matter, any number there gives the same result, cumulation over all previous values).
Also, it turns out that in order to get a proper cumsum, the option "include leading instances" must be selected, which is not explained

Steps to reproduce the behavior

Click the ? in the dialog box of Moving Transform

Additional info (worksheets, data, screenshots, ...)

Apart from a better explanation, it would help if, when selecting Cumulative sum, automatically a window width "∞" is shown, or "all rows", and also "include leading instances" is preselected
