Settings

The Settings window holds the app settings: preferences that apply to this device, independent of the project file. Every change is applied and saved immediately — there is no OK button. Scheduling options that change the calculated schedule live with the project instead — see Project Information.

Opening — three entrances, same content

• The gear (⚙) in the title bar.
• Settings (ribbon tab) → ribbon group Project → Settings.
• File → Settings (Backstage).

All three show exactly the same settings. Depending on your version they're spread over three or four tabs — a fourth, Application, has recently split off the tail end of the first tab — but the settings themselves and what they do are identical either way; this article groups them as General, Language and Timeline / Zoom.

General tab

Appearance:

• Theme — Dark, Light or High Contrast; click a card to switch.
• Font — Default, System, Serif or Monospace; overrides the interface's typeface. Web apps don't automatically follow your system font setting, so this and the next option are how you pick it yourself.
• Text size — 90%, 100%, 110% or 125%; scales the interface text and layout.
• Document switch style — how you switch between open documents: Horizontal tabs, Vertical tabs or Pill.
• Date format — dd-mm-yyyy, mm-dd-yyyy or yyyy-mm-dd. Display only; files and calculations are unaffected.
• Construction mode — Enable construction mode switches the defaults for new projects between construction-oriented (a construction calendar with Dutch public holidays, builders' holiday, phasing templates) and a neutral, construction-agnostic setup. Existing projects are unaffected either way.

Application:

• Version — the app's version number (read-only), with a Check for updates link that opens the update window. Installing updates only works in the desktop app; Snap and AppImage installs update through their own channel. Separately, the first time you open the app after it auto-updated itself, a one-off "You've just been updated" dialog appears on its own — the version jump, the installer size difference, the days since the previous release and the GitHub release notes, whichever of those it could fetch. That's a different, automatic moment from the manual Check for updates link here.
• Project information... — a shortcut to the Project Information window.
• Tour — Start tour replays the introductory tour. The same restart also sits on the View ribbon tab → Tour and in the Backstage (File → Start tour).
• Benchmark — opens the built-in benchmark tool, for measuring this machine's scheduling/rendering performance.
• AI mode — Enable AI mode shows the AI ribbon tab with the MCP bridge, so an AI assistant can work with your schedule over the Model Context Protocol; turning it off stops a running bridge immediately. Start bridge automatically (only available with AI mode on) brings the bridge live as soon as the app starts, without visiting the AI tab first — desktop app only. See the in-app AI-assistant guide for the full picture.
• Debug terminal — Enable debug terminal shows the log panel for troubleshooting.

Language tab

• Language — the app's display language, applied immediately.

Timeline / Zoom tab

• Hour planning — Enable hour planning turns on hour/minute scheduling: an hour time-scale, shifts with working-time bands and hour-precise task bars. Off ⇒ the app stays fully day-granular. With the switch on, Allow mixed day/hour planning appears (day and hour tasks in one project). If you open a file that contains hour planning while the switch is off, a bar at the top offers Enable hour planning. See Calendars & hour planning.
• Duration display — Automatic (native unit per task), Always days or Always hours.
• Task bars at interruptions — Never split, Split when selected or Always split: whether a bar visually splits around non-working days.
• Timeline axis — Show only working days compresses the timeline: weekends and holidays from the project calendar are skipped, so a 5-workday task is exactly 5 columns wide, whatever the calendar between them looks like.
• Week starts on — Monday or Sunday (week layout of the time scale).
• Show quarter-hours when zoomed in far — extra quarter-hour gradation on the hour time-scale.
• Calculation — Calculate automatically recalculates the schedule as soon as it becomes out of date, instead of waiting for F5.
• Scroll & zoom — Mode:
• Zoom + drag (the default) — the scroll wheel zooms (anchored on the cursor); drag the chart background to pan the view; Shift+scroll wheel scrolls through the rows; Ctrl/⌘+drag draws a selection box.
• Position — the cursor's position determines the scroll direction; with Screen division (Left/right, Top/bottom or Top-right corner). Ctrl+scroll = zoom, Shift+scroll = horizontal.
• Keys — assign which control (Scroll, Ctrl + scroll, Shift + scroll) gets which function (Vertical, Horizontal, Zoom) by dragging the chips; dropping on an occupied slot swaps the controls.
