Revamp editor toolbar

[solarkraft]

The current layout doesn't make that much sense.

Inspiration

Confluence

• Separates different concerns with dividers
• Highlights active item

Google Drive

• Shows an outline while editing
• Collapses sections to single icons

Word

• Clearly designed for way more features than we need & short mouse travel instead of clutter-free-ness
• Collapses items in an interesting way

Github

• Collapses all text styles on small screens
• Lacks image insertion menu item in edit mode, moving it to a bar on the bottom (?!, confusing AF)

Ricos

Confusing icons: Foot note, Code, Headings, Text style, Paragraph

Unimportant buttons: Emoticons (come on, we have emojis now), RSS feed, (paragraph)

Weird UX: Paragraph button … kind of a “reset style” button, but should be integrated into title selection where it’s needed the most
