Did you notice you can hide the toolbar with a single click in the tab strip? It's the button with a looking glass on the right. You don't even have to click the button to temprorarily unhide it - just use Ctrl+F

I'm not the person who designed this feature, but my excuses could be:
* view selector is ugly, doesn't allow combining filters and is hidden by default.
* making all filter buttons act as a widget placeable in the main toolbar would make this widget way too wide. I run Tb full-screen on a 1440px wide screen, have only one non-default buttons, and there isn't much free space in the toolbar left. Certainly not for the whole filter widget
* the menu bar may be hidden by default in future
* the quick filter bar is easy to show/hide

By the way, you may want to avoid adding comments not directly related to the bug you're commenting. It makes the comments (and the whole bug page) longer, and less attractive to read. ;)
