Hi everibody,
I need to modify the activity screen, in order to make it look like an Issue traker.
I have to add a few custom fields, this is easy.
But I also need to:
show this fields between the original fields (not in the field set).
add a comment field, with multiple records (this is available only for contacts, right?)
I thing I need to modify the tpl, but can anybody give me some tips, so I don't begin he wrong way?

Thanks!
