I noticed that the node connections are a little bit misaligned in KNIME 3.0.0, which means that the node's in- and outports are not vertically centered. Alternatively the grid is not centered. It becomes a little bit challenging to my eyes after 8 hours of work. :-D
jupp, I have to admit I am a node arranger as well. I pushed this is in bug tracking system.
Same here! But further to fixing the standard function of alignment (using the node boundary box), I'd love to have a setting to have KNIME favour a "straight connectors" alignment paradigm. This way, connector lines from e.g. a multi-outport node to a single-inport node don't turn arbitrarily diagonal (the diagonal's angle being a function of the port count difference). :-)
