Is this the same pull request? #5334

It is confusing to have several PRs for the same thing.

[mariobehling]

It complicates things if you do not update an existing PR and instead make a new one. Also please post screenshots of the changes in your PR description to make it easier to see the changes you have done.

Added screenshots...

[mariobehling]

Yes, it does the changes, but there are a lot of unrelated changes just moving code in the lines. Please revert the unnecessary indent changes.

OMG ! I think i did it. That was a nightmare to fix that indentation problem. Hopefully everthing will be good this time.
