A Citrus theme: a fresh yellow-green on dark olive, with a lemon edge and rounded text.
A new Settings window, laid out like System Settings: a searchable sidebar with pages in three groups (General, Appearance, Displays, Behavior, Indicators and Permissions; Widgets, with a page for each widget that has settings; Agents and Connections). Each page starts with its icon, title and what it's for, rows explain themselves with an ⓘ, and switches sit on the right.
Notes is your Apple Notes: the most recent notes like Apple's Notes widget, a click opens one in Notes, and a new note can be typed in the panel. Cumba reads Notes through AppleScript (Automation access, asked once), starts Notes in the background when needed and never changes an existing note. The note kept by earlier versions moves to Apple Notes once.
A To-dos widget for Apple Reminders: a list's open reminders with round checkboxes, overdue dates in red, and a line to add one. Ticks and new reminders sync to your other devices through Reminders.
Widgets look like Apple's: each one's symbol and name in its own color above the content.
Widgets are set apart by a faint line instead of cards (Appearance > Widgets: Lines or Cards).
A tab holds as many widgets as fit on the screen: the panel grows wider instead of squeezing them, and only when the screen is full does it say there's no room, in the panel and in Settings alike. The panel also grows taller when a widget needs it, such as a long answer from an AI agent, and switching tabs animates both.
Settings > Behavior > Opening Tab: open the panel on a tab of your choice or the one it was left on, and choose whether it opens on the agents' tab while Claude Code or Codex works.
The first time Cumba starts, the notch opens and writes "hello" in one colorful stroke, like a new Mac, before the welcome window. Play it again from Settings > General > Hello animation. With Reduce Motion the word fades in.
Tab bar styles (Appearance > Tabs): Compact, a bar of its own under the panel with the open tab's name; Symbols; Dots; In the Panel; and At the Top. New installations use Compact; your earlier choice carries over. Themes and tab styles are picked from cards with a small preview.
Agent notifications: when Claude Code or Codex asks a question, wants a plan approved, needs permission, finishes or stops with an error, a notification opens under the notch. It shows the agent's mark with a badge, a title that says what happened ("Claude is asking a question"), the project, one line of detail and Open, which brings the app the agent runs in to the front (or opens the panel). It then folds into the agent's mark and a badge beside the notch; questions and requests stay there until answered. Resting the pointer on a notification keeps it open.
Clipboard History shows your recent copies as cards, like a clipboard manager: text, links, images and files, each with the app it came from and when. Click a card to copy it again; right-click to remove it. Optionally, new screenshots are added as macOS saves them (Settings > Widgets > Clipboard History > Add new screenshots; macOS asks once for access to the screenshot folder).
Volume and brightness levels have their own color in each theme: the theme's colors, white, blue, green, orange, pink or purple (Appearance > Colors > Volume and brightness). Classic, Glass and Midnight use white; Neon Tokyo, Sakura, Synthwave, Violet Night and Citrus use their own colors.
A low battery (20% or less, on battery) stays beside the notch as a red ring and the percentage until the charger is plugged in. Turn it off in Settings > General > Indicators.
