Version: 1.5.8 (using KDE 3.5.8) Installed from: Debian testing/unstable Packages OS: Linux I tried to import a remote file into a class diagram (using the fish:// protocol) but umbrello replied that only local files can be imported. I think it would be a nice feature to add the ability to import also remote files.
Starting with version 2 (KDE 4) umbrello is able to use kio based urls form example https://raw.githubusercontent.com/KDE/umbrello/master/test/test-BVW.xmi, which works on the fly. Accessing ssh based urls using fish://<user>@<host>/<file> works too. If the connections requires credentials, a related dialog will be opened for requesting credentials from the user.
