Since you starting forcing the modernUI onto nodes in the classicUI, we are subject to major usability regressions on the nodes that are being rewritten:
classicUI gave you a quick hint on the datatype of the column
the new UIs, be it Row Filter, Joiner or any other migrated node, lacks this easy indicator.
Even worse, nodes which rely on you knowing the data type become more easily affected by misconfigurations hence.
Take the Joiner Node. It asks you to select columns and then asks you if you want to compare it for DATATYPE AND VALUE, but there is no way to see the datatypes in the rewritten node. In the past, the column type was part of the selection.
