Document Management

[voegtlel]

Feature request: Document Management
Details:

• Upon creating a new document, give a name directly and store in the internal database (internal file format)
• Maybe create historical versions of the document?
• Autosave background thread (saves nonactive pages, maybe even active pages)
• Create an overview renderer (opens on startup), which renders all pages in the database
• (for later) Synchronize overview with server system
  Use cases:
• User starts program, wants to continue with last document. Click on last document in overview
• User creates a new file, purpose of the file should be clear, enter the purpose as the name.
• Program crashes (e.g. computer crash). User wants to restore the document without losing data.
