Alternatively, it would already help to have a "edit" directly after the listing of all Action Items. Now the action item is shown, with a {{{1}}} for the link to the file. If the link to the action item '1' could be extended with 1?action=edit than it would make the action item closure "one click shorter".
Unfortunately there is no way to perform multiple automated edits to do this.
I have added into the IoTSec AI template a "Click to close action" button. This will perform an auto edit that sets the status to "Closed". So at least you can quickly close actions without having to go through an edit cycle.
I tried adding it to the query template so you could close directly from the actions list, but unfortunately this does not work. Parser functions in queries rarely do work unfortunately.
