Trunk Notes should turn what it thinks are links automatically into hyperlinks, e.g. http://www.google.com
should appear as a link
The differentiation of links is a good idea, I have added this to the current development branch of Trunk Notes. I like suggestions which take minutes to implement ;o)
As to the idea of an internal web browser see viewtopic.php?f=12&t=461
for a workaround. It would be fairly straightforward to implement properly although it may require that the age rating of Trunk Notes is put to 17+. Apple have some fairly strict policies on age ratings... I will need to investigate.
