Domino Volt is a low-code platform. The designer should be able to create apps with no or little coding, without the need to learn a programming language at least for simple apps.
But even in the step by step tutorial, when tables are introduced, you have to enter (or paste) four lines of code for the most common reaction on selecting a table row.
Therefore I think, to get more non-programmers involved in the platform and have success, it's essential to find this kind of typical, high-frequent event handling actions and give the citizen developer an easier way to use them: simple actions.
In the tutorial example: create a simple action "set field on table selection" with as a minimum the name of the field to be set and the column of the table to get the value from. And an optional call of a service after setting the field's value.
