Unified header

• Combine viewer header and the text formatting menubar (similar to how it is done in Nextcloud Office now)
• Combine the Share icon and the avatars into one overlapped thing. When we have avatars, we don’t need a share icon at all, and they don’t need individual clickable area – all can open the sidebar. (Mockup in the works)
• For Shared links, even put the controls in the blue header bar – see Dropbox Paper. (Mockup in the works)

Here are the mockups:

Unified bar Viewer + Text when logged in

We should also combine the Share icon and the avatars into one overlapped thing. When we have avatars, we don’t need a share icon at all, and they don’t need individual clickable area – all can open the sidebar.

For Shared links, even put the controls in the blue header bar

Mobile

Smaller polishing before the rename (already done):

• Flash of half-transparent black at the beginning of viewer open should be white instead. https://github.com/nextcloud/text/pull/1907
• Title and icons on top right shouldn’t fade out

Start with the viewer header and text formatting menubar, then compare the logged-in and shared-link mockups in the issue, including desktop and mobile layouts. The work is done when the headers and sharing controls match the described unified-bar behavior, including the avatar and sidebar interactions.
