Propose design improvements on main Search UI

The search UI could have some improvements done to its UX, like the following:

• Small actionable space on the filter's navigation, it only works on the small arrow to the right of each panel, ideally the whole title should be actionable.
• Better wording on technical terms like "facets"
• Create and edit buttons don't make sense here. If possible, we should at least hide them for regular users.
• Odd breaking of words and options on filter options. Depending on word length, the checkbox is separated from its label.
