Service Studio > Top-right search box: When you type some text, which is not immediately recognized as ation/entity etc., the default action is "Search forge". So if you type text and press Enter - the forge starts to open (in previous version it was "search comunity", I think). To search in the eSpace, you have to specifically select this option with your mouse (or keyboard).
I believe that text search over the eSpace is much more popular usage of this control than searching in forge. Personally, when I actually want to find something in forge (which is quite rare) - I don't even use this functionality, because it doesn't come to my mind. At best I would go to "outsystems" menu, or open the site.
So I think it would be better if "search for text" is the default option there, and you don't have to navigate to it every time.
