I have just used the "save as" button for the first time. Great idea and I was looking for it for a long time...
I am using the KNIME Windows 64bit ( 2.9.0) developer version.
After clicking on that button a lot of things happened that took quite some time. This involved all other workflows that were open, not necessarily loaded though. then when i came back this morning I was able to give the new workflow a name, which I did... The result was a new folder with that name in the subfolder out of which I created the save as workflow. and a SVG file (workflow.svg). After closing and reopening KNIME the workflow was gone and I am left with a svg file...
Did I miss something?
