Your folders, and what's in your documents.

Every document has a type, fields such as payee, amount and due date, actions and tags. The table shows them as columns; which ones, in what order and how wide is up to you. A view with its folder, sort order and search becomes a bookmark.

In Edit mode you change type, tags, fields and actions right in the cells, for one row or the whole selection. Derive from the text fills empty fields without a model. Saving is one step.

Words, "a phrase", -word, plus keys: type:invoice, due<today+7, $pay:open. The columns follow the search, and as you type, Undan suggests examples from your own archive.

On the left are the open actions with their count — Pay 3 —, the types, your own views and what you have pinned. Every rubric is a search, always up to date.

PDF, images, Markdown, and Word, OpenDocument and Excel as pages too, without anything else installed. Plus the recognised text, printing and a window of its own.

Edit… places text, a date or your signature on a page. It places, it doesn't rewrite; Ctrl+Z brings back the old version byte for byte. Password-protected PDFs you can view without Undan storing them decrypted.

Next to every document is what belongs to it: notes, tasks, emails, contacts, appointments — each with the reason, such as “came with this email” or “same IBAN”. Calculated, not guessed.

Deleting means the Trash, 30 days by default. Every step is in the journal, and Ctrl+Z takes back the last one, even after a restart. Dragging files out into an email or a web form never deletes anything.

Tree, table, preview, relations and fact sheet each have a key; the command palette finds the rest. Every key can be reassigned.
