The schema mini view on the bottom navigation tree of the query editor

Common users want to see columns and ddl informations when he/she select table or view.
It would be better to use if it shows columns or ddl information on the left bottom of the query navigation tree.

Reqiurements:

• If you click a table on the tree, it's colums information should be shown on the bottom tab.
• If you select multiple items, it should be clear information on the view.
• If you select except tables and views, it should be clear information on the view.
• It can be supported options on the preferences if some user did'nt to want this function.
