Panels and layout

The parts of the window#

The menu bar across the top: the Semantix mark, three menus, your profile, and the window buttons. The empty space in the middle is a grab handle — drag it to move the window, double-click to maximise.

The left sidebar holds two tabs, the explorer and search, with a few more buttons beside them for extensions, automations, and the two full-screen modes below.

The middle is your open files and the 3D view of your project, with a tab strip above them.

The right sidebar is the agent. One conversation, docked.

The bottom panel is the terminal and the server log. Hidden until you ask for it.

The status bar along the bottom shows your project name and, next to it, either how indexing is going or the size of whatever you're looking at — folders, files and edges for a directory, symbols and relations for a file. It's a readout; there's nothing to click.

The menus#

Projects — open a project, close the current one, and a list of the ones you had open recently.

User — settings, plus the things that open in a window of their own: the theme editor, your usage statistics, and others.

View — three toggles, all with shortcuts: Toggle Explorer (Ctrl+B), Toggle Agent (Ctrl+Shift+A), and Toggle Gizmo (Ctrl+Shift+G) for the little orientation cube in the 3D view.

Your profile is at the right end of the bar, with the account you're signed in as.

Moving things#

Every panel resizes by dragging its inner edge. There's no visible divider until you get close to it, then a line appears and follows your mouse. Sizes are remembered.

Drag a panel far enough shut and it collapses to a narrow strip with an arrow on it — click anywhere on the strip to bring it back. Panels always start expanded when you reopen the project, whatever you left them at.

Panels can't be moved to other sides, and tabs can't be dragged into a new order.

Ctrl + and Ctrl - resize the interface and the editor text together.

Floating windows — settings, statistics, and the conversation cards in runs mode — can be dragged, resized and maximised, and Ctrl with an arrow key snaps the active one to half the screen. They can't cover the menu bar or the status bar.

Where the conversation sits#

The agent panel on the right is one place. Another turns every open conversation into a floating card over your project, all of them live at once, driven by a single command bar at the bottom.

Both of those are chosen from the view-mode button in the chat input's toolbar.

→ Runs mode

Two full-screen modes#

Two buttons in the left sidebar's icon row replace the whole window rather than layering over it:

• Chat — the conversation, full screen, nothing else.
• Agent Composer — the canvas for building agent flows. Its top bar has an IDE button to come back.

Both genuinely put the 3D view away while they're open, which is worth knowing on a slower machine.

→ Agents

The tab strip#

One tab per open file or folder, plus a permanent globe on the left for the project root. Right-click a tab for the file actions and for Close, Close Others and Close All.

→ The editor

What comes back#

Reopen a project and you get your open tabs and the active one, your panel sizes, your folder open/closed state in the explorer, your scroll position in each file, your fonts, text sizes and editor theme, your keybindings, whether the bottom panel was showing, and — if you were in runs mode — the mode and where each card was sitting.

What doesn't come back: side panels you'd hidden with Ctrl+B or Ctrl+Shift+A (both start visible), the gizmo, collapsed panels (everything starts expanded), your terminals, and your cursor position and undo history in a file.
