I started looking at KNIME 5.1 on Linux using the new GUI. How can I install new nodes and see what is already installed? In KNIME 4.7 this is accessible via ‘Help → Install New Software…’. Probably missing the obvious…
in linux/others, just to know the installed extensions/nodes,
a. look at right-top corner for symbol 'i"
b. select “install extension”
c. click on the link “what is already installed”
