On "Parameter Declaration" tab page of Beautifier's settings I found option "List at left margin".
Unfortunately this option has effect only if more then 1 parameter is presented.
Is this an error or that behavior was it conceived?
Thanks!

This is indeed by design.

Thanks Marco,
"List at left margin" option let align ALL procedures and functions with each other, regardless of the length of their names, their parameters, or their return types.
When it depends on number of parameters, we get a mix of alignment rules.
Where is the essence of that design idea?
I would be inclined to believe that this is a bug...

The idea is that 1 item is visually not a list, so it does not have to be visually aligned as such.

I have added this to the list of enhancement requests.

i am going to enter the fray here ...

Interesting premise, one item does not make a list, but I disagree.

I have been asking for this for ages. I am a fan of consistency and this breaks all the rules. Even it's a list of a single item, it is still a list and should still follow the same rules as lists of more than one item.

maybe there’s a chance to see it in the upcoming 15 release?..

please? will even send you a beer ...
