Site Layout Ideas

Some ideas for the layout/features of the site.

User/Site bar

Title: Optional title
Language: Language select dropdown
Custom URL: Auto-generate normal random URL if blank, do AJAX check for if already used
Child of: Text box for id of parent code
Password Encrypt Page: Checkbox, client-side encrypts code and comments; if checked reveals:
Password: Text box for password, is never sent to server
Server stores a random salt (UUID) which is sent to the client
To decrypt, client hashes key+salt and send hash to server. If hash matches server-stored hash, server sends code + comments, which are decrypted client-side with key.
Hint: Hint/Message to prompt when encrypted page is visited

User/Site Bar on top
Code on left
Comment numbers in little bubbles to the right, aligned to code. There should also be bars that give information like "2 comments on this line by Alexis". When a bar is expanded to show the comments, the other bars disappear but the bubbles remain.
There should be a seperate "comment meta-data" JSON file that is just a map from line numbers to number of comments, as well as possibly some preview text to use. Only this is loaded on initialization. Actual comments for a line are loaded only when clicked. at a time. 10 at a time, with "more..." button to load next 10. The metadata may be live updated, but this is perhaps excessive.
Comment display/writing the same
Merge button on bottom: generates code with all diffs accepted
Merges would be displayed to the right of code, where comments had been.
Removed lines would be highlighted red in the original code.
Added lines would be highlighted green in the merged code.
Next to merge, if merge has been pressed, submit merged code button: go to submission page with relevant data
