I pondered the idea of text import/insertion, would be cool to be able to
import loads of text and split it up into differnt textboxes based on
linebreaks or other string tokens.  For something as much as 500 records

The file isn't encrypted, it's simply gzipped.  You can either uncheck
the option of compressing files when you save the diagram, or
uncompressed the file using gunzip.

I would humbley suggest that to avoid these kinds of questions in future
that gzip compression be off by default.

What are the reasons for having it on by default?

The reason is that XML files tend to be large and very compressible.  For
instance, the 15K compressed file samples/AST.dia uncompresses to 600K, a
factor 40.

If diskspace is really a concern (and i have started to notice
the cumulative effect of almost never compressing my files) then
being able to save as .dia compressed with bzip2 would be a nice

The difference between gzip and bzip2 is a small amount of size and a
somewhat greater amount of 

I quite like the way Abiword has gzipped abiword as a seperate file
format (.zabw).  Adobe Illustrator (amongs others) has gzipped SVG as a
seperate format (.svgz).

It also makes things simpler when programs dont use the same extension
for different contents, but i should know better and use "file" instead
of crude guessing based on file extension.

I agree that having a different extension would be nice.  Maybe .diaz?
.zdia?  I prefer .zdia.
