Reworked toggle view

Previous:
- It would just hide the overlay dock widget and leave the side tabs
still visible
- Close button, toggle view action would simply collapse the dock widget
intsead of completely hiding it

Current:
- Now toggle view and collapse functionality are separated.
- Toggle view will now hide the side tab bars completely
- Close button and toggle view action will completely hide it
- Collapse view will simply hide the overlay dock container without
hiding the side tabs
- Handled logic for floating widgets and toggling view
