Even I sometimes forget that I have a predefined view on a list to support a process. In the older versions of SharePoint the views were display as actions on the left of the list. Now they are hidden in a drop-down which is often scrolled off the screen if there are a lot of columns in the default view.
This happened to me today when I was talking to someone who said they had web page listing all the SharePoint related KB articles and hot fixes. That reminded me that I also had these KB’s listed in my resource list but you would not see the pre-defined view unless you found a page on my site that had the tool bar visible (not often the case).
So I added the view url to the top menu of my site. This made me think that there might be a better way of showing the views available in a standard list page (another demo to add to my to-do list).
