Tags are one of the basic tools for organizing documents. When working with tags in Keepmark, you can start by defining a list of tags for a given workspace, or simply create them by assigning to documents right away. All tags assigned to documents will be visible in the application's side-bar, allowing you to quickly filter the list of documents to selected subjects.
In Keepmark you can add relations for an existing document, to other documents, tasks, or people. This can be done through the side panel of an open document.
In Keepmark you can configure other external tools to work with. Mainly, I can be other applications, or shell scripts run for the selected document. Before you start you should configure them in Application Settings.
