Aaron Seigo describes the development plans for the Plasma framework. "However, in Plasma Active we've made two purposeful decisions: do not expose the hierarchical file system (unless the use case dictates that as a requirement) and do not expose details that are not relevant to the usage of the device (e.g. I care that I can open that spreadsheet, it's less important at that moment that the application is Calligra Sheets). Thus to open a spreadsheet one opens the file manager and goes to Documents, or simply searches for the document from the Launch area directly. No file system, no application launchers."
