Vertically splitted tab with single (not splitted) horizontal results grid

If I split tab (sql query text editor) vertically it also splits current schema and results. But the purpose of splitting tab is not comparing results from different schemas but more effective editing. If I would want to compare results I would just open new separate tab.

What I want is an option to have splitted vertically sql query text editor and results grid which is not splitted and have full width of current tab as if tab was not splitted. Right now I use standard query formatting and it ends in a lot of unused editor space. By splitting text editor vertically I am utilizing unused space. But for a results grid more width is better.

An alternative is detach results grid and change its width manually but I'm not sure how this detached grid will work with many tabs opened.
