I have just found the software yEd - looks very good.
I need a software to make svg-format files to put on the web in a mediawiki.
I see that I can do this nicely with yEd. My problem is this:
I open the svg-file with Firefox and want to go back in Firefox - not that the svg-file opens into a new window in Firefox. I have not found ot how this is done - Is there a button somewhere to fix this - or can I not do this with an yEd file?
