Manual relationship editing/notes addition

I sent most of this in the contact form, and just now found the forums. Sorry about that! It is almost 4AM here ... I''m slightly tired.

I am currently using Maltego to find relationships between certain websites, which is working better than expected. However, one of the things I do is I look at the source code in a given website and find links to offsite JavaScript files, images, etc. Is it possible to manually draw the relationship arrow between the newly discovered website and the original?

Next, in my research of these websites, I am finding similarities in the websites in things such as text, images, the offsite websites they link to, etc. Is it possible to have custom fields to add and link the relationships to? For example, I have found one website that has the exact same image that is from another, and claims it to be unique, but given that these two websites have the exact same image (in this instance, supposedly unique to the given website), they are at least weakly related, and I would like to show that. Perhaps an "evidence" field to support your reasoning behind why you are manually linking the two entities.

Also, would it be possible to add notes to each entity and globally? For example, if I have to stop my research, leaving myself a note in Maltego on where I left off would be great. Also, adding notes to each entity on things I should manually research later would be great as well. So having notes fields for both the global view and each entity would be great.
