In the name of all Umbrello developers I like to thank you very much!

I think now there are RPMs for Suse avaible. Please have a look at the
homepage again into the file section (sf.net/projects/uml). Maybe you should
also subscribe to the Umbrello announce list to get automatically informed
about new releases and about prepackaged versions.

I will add the first problem to the bug tracking system, so that every
developer gets to know about it. You than can follow how we resolve the bug
or if we reject it.

I can't say very much about it, I think we will see what the UML gurus are
saying about it ;-) As I said I will submit it for you.

I think this bug have been fixed. You meant right clicking on the assoc and
choosing a operation?! Yes, this works now.

You mean parsing existing C++ code and getting the initial value? Well, I
have to say this isn't very easy. The whole parsing code isn't very good and
I think we can't improve it till the 1.1 release.
