I have built a small module that really would fit better with views_bonus. Please take a look at it and see if it might become part of views_bonus. I applied for a cvs account trying to make this it's own module, but it's a bit thin to be a full blown module when it would fit in here nicely.
New Views Filter that creates an exposed Multi-Select filter of the current view's Node Titles. Allows user to filter by node titles. I needed it for a current project and found a few threads of others looking for this as well. This filter only works as an exposed filter. My hope is to get collaboration to improve this filter and to continue to contribute back to the community. I have not found any other modules that provide this view's filter.
