This is unpractical.

Not really

Add a clear information

It doesn't kick you from the Limesurvey, you need to use back in history button in your browser and you will still be logged in.

@DenisChenu do you think we should add a confirmation modal or something similar to open the link in same tab?

We are inside a form here ? Not really since it's the list and we don't have real form (no save button)

Then maybe ! if we want to open on a new window

1. Add a clear information : adding (this link open in a new window) after the text.
2. We can hide it via dedicated css and replace it by a font-awesome icon for example.

I don't have a strong opinion here.
