This probably has been requested in this or that form but I cannot find those threads now.
Please add a capability to define an On change action on each control or table column.
The action would fire right away in a user’s browser when they change the value. It should only execute on changes made by current connection and not on changes coming from other users / other tabs by the same user.
We have automations that can watch over changes, but they don’t run instantly and are generally harder to set up. Adding the proposed capability not only would solve this but also reduce the load on the server-side workers and generally offer better UX. It would be possible to build scenarios where e.g. changing the first drop-down in the series would reset all the latter drop-downs for re-selection.
