Data app can be opened and executed in another tab, just like what knime is using new tab style for other workflow and component view.
I think it will make the knime somewhat capture the “BI market”, But I do not understand, why still categorised node bar is not redesigned in new knime 5.1 or 5.2.
Knime has done a lot, now I can develop an complex data science model within minutes. But it is still not modern like power bi pr tableau in case of UI and UX.
