With the great additions to make computations based on previous responses, the question may arise: when is a survey completed?

For example: when answering quiz-like questions and reaching a last group (or groups...) where the results are being shown in text display questions, you may consider a survey to be completely filled in.

Can we imagine to add a feature that gives the survey designer the possibility to state at what point a survey is completed?

And: when the users reaches this featured end point, the date & time is written in the database.

What addtions do you mean?   Just to understand the motivation.

Even under older LimeSurvey versions there is a gap which could be filled by a terminate question type.
This questiontype could be placed anywhere and would come with a few options.

First, the questiontype would write a Statuscode/Depositioncode into the response set.
Typically you numbers with certain meanings in survey tools.

Complete/Qualified
Disqualifed
QuotaFull
etc.

That way you could easily see, why a response set it like it is.
Beside the status code, you would allow to define a another code, which would be saved into the response set as the answer to the termination question.
Another option needed, you be the destination of the termination question.  Endpage of survey or external URL
 

I meant the additions like:
manual.limesurvey.org/StatFunctions
 

I use functions like these to make up a last page like here:
research.respondage.com/index.php/774648...t=Y&lang=nl-informal
But when the user is here, she does not proceed, thinks this is ready now.

I really think LimeSurvey core must allow submitted survey when "Submit" is done …

Maybe we can add a new function
Some think like this

statCountIfCondition(QuestionCode.sgqa, value[, 'submitdate is not null']);
