hmmm doesn't seem to work for me. I just created a new project without
ticking the marco checkbox and when I open it I get the warning.

Yeah I think it can be a security issue also however there are some
things that reduce it:

 - The project file is plain text so you can also check ones that you download
 - In places like where I work we tend to only use internal project
files so it's fine to have it always enabled
 - IMO the chance of someone doing something bad with them is small I think
 - Word and Excel store everything in binary and hence have a always
on option is a huge risk as there is no other way to check the code.

I agree however I think the risk of a swap is low of a swap IMO.

I quite like the lack of a icon on the close button. It draws your
attention to the right which is where the user should look.

There are some nice icons here
http://www.iconfinder.com/search/?q=warning I use them in a lot of my
projects (just check licence)

I'm also thinking that I might be good to have a light yellow bar for
warnings, light red for error, and light blue for information.  Pick
the main colour of the icon and change it enough so the icon and bar
stand out.  Like this

I think people will be very happy with addition.
