With the release of 1.6 I decided to modify this form, http://www.eandhbaxendale.com/online-enquiries/easi-joist-enquiry/ to take advantage of the new list field by making it easier for customers to enquire about more than one joist size at a time. I also decided to take the opportunity to add tooltips to some of the fields using the tipsy jquery script, I was originally planning on adding the tooltips directly to the fields so when the user tabs into the field the tooltip automatically appeared but in the end I decided to use the help icon from the admin side (hope that's OK). I have ended up using a function http://pastie.org/2854276 to add the necessary icons and title attributes where I wanted them which seems to be working well.
Now to the question would it be possible either by extending that function or by adding another or some other script to modify the title tags for the add and remove row img buttons so instead they say 'Add another easi-joist' and 'Delete this easi-joist'
