after the last upgrade i notice the toolbar is differently rendered.
BEFORE
when i open a grid in a tab from the menu, the button BACK was not shown.
AFTER
The button back is shown. it makes no sense for tabs/menu.
The button exist in the toolbar as EXIT type, it was shown when a grid was opened in a new window for instance. but not in the menu tabs.
if the user clicks BACK, the whole app is shown in the tab, include the menu, u get app in the app.
