Comment 8 for bug 1573031

Most tool bar buttons are never or rarely used.

Only frequently used buttons shall be shown by default. And only when it is not more intuitive than the right click menu, like when copying and pasting or per object action.

The status bar can also be hidden in some of these applications, the same as the sidebar contracted by default.

Here are some suggested defaults:

Good interface design shows what is currently in use in that very moment, or used constantly. And gets rid of everything else.
