User interface
Every item opens on the same page: a title, a row of tabs, and one bar of actions. The tabs carry a count, so you can see what an item has before you click.
The action bar is the same everywhere and has four controls. Edit and Print do what they say. Analysis collects the views that read the item rather than change it — failure analysis, fault tree, checklist, risk model, Gantt. The ⋯ menu holds everything else: revisions, exports, QR, import, copy.
Reading
Any document can be read as a page rather than as an application: one centred column, serif, justified, and nothing else on screen.
Mathematics is written in LaTeX and rendered by MathJax, inline or displayed.
Dark mode
Every page has a dark variant. It is a setting, not a separate theme to maintain — the same templates serve both.
On small screens
The layout is responsive: the sidebar collapses, the action bar stays, and wide tables scroll inside their own container rather than pushing the page sideways.
Colour means something
Colour is not decoration in KF, and this is worth knowing before you read a screen:
- Green, orange and red are status only — done, pending, missing. If something is coloured, it is telling you the state of a piece of work.
- Grey is page furniture: the icons in the action bar, the tabs, the chrome.
- Light blue identifies the class of an item — document, object, action, event — and appears in the navigation bar, where it is contrast against the blue rather than meaning.
So a red mark on a checklist row is a real signal, and a blue box beside an item name is just saying "this is an object".
