Use checkmarks inside view menu instead of "show/hide"

This is not very easy to visually scan:

Show Sidebar
Hide Statusbar
Hide Tabs
Show Console

Dependent on the visibility state of an interface element, the verbs in the View menu change.

Using checkmarks would be much more comfortable

    Sidebar
✓ Statusbar
✓ Tabs
    Console

The menu entry would start with the name of the affected interface element, always at the same position, easy to scan which element is switched on or off
