Haha, I know six of your testers pretty well! There are several glitches I've found and have some suggestions, here's a link to my Zendesk post:

Jeff: Thank you for your feedback! However your link doesn't appear to work. Can you post another link?

@John I assume this one https://khanacademy.zendesk.com/hc/en-us/community/posts/219304227-New-Programming-UI-feedback since it was made about an hour before his comment here (found by clicking his name and scrolling down).

Benjamin found the correct link, thanks man. I guess my browser hadn't updated the URL when I pasted it here.

So many things in this area feels broken.  Not sure where to report it.

*Some of the challenges will not load, loading circle where the instructions and hints are for days.  

*I am a teacher and I generally complete a challenge and restart it a million times for the students.  Now when I restart a challenge it is not letting me advance to the next step even though its correct so I have no way of walking a student through it if needed.

*Starting a new blank project is a pain now because they have to go back to the main CS section to open a new one.  

*The image that shows after you have successfully compelted a step covers up the side with the code, over the code, and then wont leave at times.  

Im sure there is more.  Love KhanAcademy and having it broken is messing up my classroom flow.  ;/

I'd like to add a suggestion.

The pages are a lot bigger now. It would be nice to have the different sections of the page to have an ID, so we can use them as bookmarks.

That way I can tell people, for example, where to go to create a new program, and they don't have to scroll all the way down.

Now that I'm using the new interface a bit more I really do not like it. Here's why:
1) the programming window and canvas no longer use the full width of the display. I looked at an old program of mine and no matter what zoom factor is used I cannot see as many characters per line as I could in the past and now many of my comments are wrapped even though some of the lines were only perhaps 70 characters. Providing huge left/right margins on widescreen monitors is completely misguided. It reflects a silly attempt at "neatness" at a significant cost in capability and loss of user control.

This revamp of the layout has some okay design elements but this arbitrary restriction of the width of important page elements is a defective MEME and the totalitarian instinct that chooses to impose this limitation on the whole community is truly destructive. I've seen this same scenario play out on once terrific websites in the past. It is sad when actual users are harmed due to the imposition of some design concept poorly learned in some freshman web design class. There really should not be a maximum pixel (or other absolute measure) width on the code window.  It should grow as the browser width is increased. I could see perhaps a 5 or 10 percent margin but not a 800 px max width (or whatever the actual value is)

2) the ability to select and make the code area taller has been lost. The cursor still changes shape at the bottom of the code window but the edge cannot be dragged like it could before to allow a tall coding area suitable for portrait oriented monitors.

3) the documentation area also seems to have been reduced to two columns and now takes forever to get to the bottom. I may be remembering this wrong but it seems like the system used to be able to handle more columns in the layout if the width permitted.

4) the buttons for Settings, Voting, Deleting and Share now behave in horrible ways. For example, if I click on Settings, the pop up appears as usual but the buttons change their layout so that the cursor which hasn't moved at all is now on top of the Delete button. If one clicks again the delete dialog pops under the settings dialog and if one is not careful disaster could ensue.  Sometimes modal dialogs are okay especially when the actions are logically mutually exclusive (like deleting and tweaking the width of the canvas)

Along with @Chrisrennick56's response with details about settings, voting, delete, and share buttons, there is a flagging bug left over since beta. You can flag a program multiple times by switching to a new tab (as in about, documentation, spin-offs tabs) on the program. All flags made after the initial one don't count but this still is broken.

@Chrisrenick Your "poorly learned design concepts" comment just fits with what I see and hear from KA.

Re the arbitrary screen size, I'm coming at the problem as someone trying to get children programing. Like a child's first attempt at painting, they need as much canvas as can be spared when starting out. The small editor window is like trying to paint a mural on a scroll. They don't have the mental map yet to remember what was above and below and the constant scrolling up and down to view their work just saps enthusiasm and turns what should be fun into work.

All because some designer wants the screen to fit neatly on their phone.

There seems to be a flagging issue using IE 11.  None of the flag links I have tried have worked.  I have tried several: Recent Posts questions, various comments locations, Project Help questions and even Project Evaluation screens.  ( I've seen several projects passed evaluations even while the project was unfinished )
