Currently there is no way to change the number. There are 20 on a page, unless you mean the number of page links which is 10. They can be sorted by the relevant attributes to get the ones you are most interested in to the top.
From my perspective I also have to consider that increasing the number puts strain on the server, particularly in skills view, and those are resources better utilized for other tasks. At this time this would be a very low priority for us, and there is no need to change it right now.
