I would like to add a field on the HOME page of "Files checked out to me" so that users can see what they have checked out.
Why not use Relevant Document web-part.It is inside Content Rollup category
When you edit a Relevant Documents web part properties, you will find the following options under "Data":
- Include documents last modified by me
- Include documents created by me
- Include documents checked out to me
Third option will display all documents checked out to the currently logged in user from within that sub web(not entire site collection)
