Restore from curved conections

Dear Knimers,

I have recently upgraded from version 4.7 to 5.2 (which made the platform significantly heavier on my machine (with an Intel i5 processor and 20GB of RAM-memory).

But my request is for help on choosing for uncurved connections.

Can someone enlighten me to find a more complete menu (such as the former, that was much better than the current one)?

Any help would be much appreciated, even (in a last case) on how to install a former (and lighter) version of Knime.

Thanks.

Rogério.
