Stops the "WordPress x.y is available" banner from showing to users who cannot update WordPress, so editors and authors are not distracted by it.
Hides the Screen Options tab for everyone except administrators, so other users cannot rearrange or hide admin panels.
Starts everyone with the narrow, icon-only admin menu for more working space. Users who expand it keep their choice.
Tightens the spacing of admin table rows so more posts, pages and users fit on screen at once.
Shows a small floating Edit button in the corner of posts and pages for users who can edit them, which is handy when the admin bar is hidden or on phones.
Hides less useful columns for users who have not customized Screen Options yet. Anyone can still turn them back on.
Hides chosen plugins from the Plugins screen for everyone except the users you name, so clients do not deactivate them by accident.
Adds a small search box to the admin bar on every admin screen that searches posts, pages or users, and jumps straight to the editor when you type a post ID.
Applies the same admin color scheme to all users and hides the color picker on the profile screen. Handy for telling staging and production apart.
Users who cannot edit other people's posts, like authors and contributors, see only their own items in the admin lists.
Keeps the column headings of posts, pages, users and other admin tables visible while you scroll long lists.
