The query is about setting the location of a custom toolbar. When the toolbar gets placed using the hiPlaceToolbar function, there's this option to mention the location - top/bottom/left/right.
But, it gets placed along the same row of toolbars which are already there - thereby getting squeezed to a corner. How do I set it to get placed on a new row automatically and always?
No - I can't do that. It's a public forum, and the point of a private API is that it may change and we wouldn't want customer code to break due to them using a private function. We occasionally give out private APIs if they are going to be made public in the near future, but this really must be accompanied by a CCR to request that it becomes public.
I'm also not 100% sure that the private API I found does exactly what you want anyway (without further experimentation; if you're going to contact customer support anyway, it would be better the AE there does that as I'm a bit short of time to do detailed investigations right now).
