I have a few issues with the Table of Contents and with the List of Figures

1 How can one force a page break after some section. In my present setup I have a Chapter 4, sitting lonely at the bottom of the first page of the ToC, with its sections on the next page. I have tried \completecontent[3.7], as described on p. 53 of "ConTeXt an excursion", but that does not work for me (I'm on mkiv). 

What can be done about it?

2 My list of figures gives the complete captions, some of which are long. Those exceeding their allotted space break off, which is OK, but there are some that run up against the page number, which is ugly and unclear. 

What can I do the create a little more space between caption and page number?

In general, of most if not all of the 38 possible arguments for \setuplist, as shown on http://wiki.contextgarden.net/, I do not know what they do and how they can be used. Unfortunately, also "ConTeXt an excursion" is very brief on this subject. 

Is there any place where I can find more information?

Thanks in advance for ay advice.

Best regards,
