Most of users want to use query editor in CM and CQB,
However I think it is hard to open the Editor. Therefore I should click-right on the DB name, and in the sub-menus I have to click "open the query editor"
Opening a query editor must be easier.
<open the query editor> menu should be in sub-menus in the table item on the tree.
When double-clicking the <table> item, query editor should display over the cubrid news page.
Query editor should be default on the right screen.
When I open CM, <cubrid news page> is displayed. If I close the window, the query editor should be displayed on the bottom.
When I double-click the <DB> name, it displays DB storage status. If I close the window, the query editor should be displayed on the bottom.
Currently there is empty screen if I close those windows.
