Content creation

When I drag an object to the dropping zones, the right zone gets a colour. See attachments. How can I change this?
Thanks for your reply.

I use Drag the Words (in Course Presentation) to let students order the steps in a process. Now I discovered that answers with many characters, for example "Stap 2: *Omgeving object observeren* " are being cut off, in this case: to 'Omgeving object o...' (Check the attachment.)
What can I do to change this (except using smaller descriptions ;-) ) ?
Thanks in advance.

New interactive videos can be created within a Course Presentation. Is it possible to insert an interactive video that has already been created? Similiarly is this possible for Fill the Blanks as well? I'm using wordpress and I had created a few stand alone resources, but I'd like to embed them within a course presentation, rather than recreate them from scratch. Thanks.
