GUI v2: MVP

[apyrgio]

Main issue: #885

Before we start implementing every little detail that we mention in the GUI v2 issues, we should think which are the features that we want to push immediately to our users, and what shortcuts we can take to get faster there. Assuming that the UX makes sense, then the rest of the UI touches will follow.

Proposed issues

• Start with GUI v2: Footer #886 and just move the burger menu and Dangerzone version to the footer. This way we can then repurpose the space that is now taken by the Dangerzone logo.
• Continue with GUI v2: Alert popup #888 and implement as many UI changes as we can within a timebox. The idea is to get a feel for how easy it's to follow the aesthetic of the designs.
• Continue with GUI v2: Document pop-up #890 and implement it fully. It's quite small and some of the UI elements will be taken by GUI v2: Alert popup #888.
• Continue with GUI v2: Drag-and-drop interface #892 and implement it fully. We already have a drag-and-drop interface, so the changes will be small.
• Continue with GUI v2: Document conversion interface #893, and heavily base it on GUI v2: Drag-and-drop interface #892. This way, we'll get the header and footer for free. We don't need to implement the zebra rows and other visual cues, but we must implement the feature that adds documents to the list while they are converted.
• End with GUI v2: Document row #891. There are lots of changes we can do there, but let's focus on the following small wins:
  • Add "View" button
  • Add "Estimated conversion time" (only if Perform on-host conversion for the pixels to PDF stage #748 is merged)
  • Add "More details" expandable section, with just the following info:
    • Full safe file path
    • Full unsafe file path
    • OCR info

Expected features

The above MVP will bring to the user the following features:

• Add files after a conversion has started.
• Per-document settings
• Estimated conversion time

The features that this MVP will lack are:

• Welcome page
• Conversion logs
• Instant file previews (but this feature needs a lot more scoping)

Remaining work

At the end of this MVP, the status of our issues will look like this:

• 🌘 GUI v2: Footer #886
• 🌑 GUI v2: Welcome page #887
• 🌗 GUI v2: Alert popup #888
• 🌑 GUI v2: Default settings #889
• 🌕 GUI v2: Document pop-up #890
• 🌘 GUI v2: Document row #891
• 🌕 GUI v2: Drag-and-drop interface #892
• 🌖 GUI v2: Document conversion interface #893

(progression from "todo" to "done" is 🌑 -> 🌘 -> 🌗 -> 🌖 -> 🌕 )
