Stage Based Challenge List View

[AmusedNetwork]

Whilst using another CTF platform, I found this layout to be enjoyable to use.

A few of the features I liked while using this design:

1. All challenges are displayed on one page
2. Page automatically updated as new challenges were unlocked
3. Page can be Ctrl+F'ed to find prior information
4. Hints are displayed in a list view below the submission box for each challenge
5. The amount of hint left is clearly displayed
6. The amount of points lost (by answering incorrectly) is displayed prominently
7. The amount of points available per challenge is clearly displayed
8. It is easy to tell whether a challenge has been solved or not
9. All challenge descriptions are expanded by default
10. Clickable category/stage list on the right to quickly jump to another stage.
11. All hints are displayed after correctly solving a challenge (although this is not completely related to the UI)

Another benefit of a one page design is that it can be saved by the user by using CTRL+S in a browser. This is more of a quirk of the platform I saw this on, as the CTF can be closed overnight / between sessions and it can be useful to keep a list of challenges to work on offline.
