lts support disappeared with net 5

I have an existing fiddle (https://dotnetfiddle.net/aLU0Z8) and try to change compiler cause a feature is missing (proprerty initializers) and when I do it it just clears the script and goes to the root url as if I was making some new fiddle. I had to copy-paste content from the old fiddle to make this one that compiles ok - https://dotnetfiddle.net/W9zCSm

If you are typing in fiddle, and then realized you hadn't logged in yet, and then log in..POOF there goes all the work you've been entering for the past however long. Can you fix this somehow?

White background hurt my eyes. Only keywords coloring is not enough for code coloring.

Tidy Up is great function but I've noticed that if I'm working on a Saved code and I hit that button, the code formats and then my save button disappears..

Support for System.Diagnostics.Debug.Assert could be added. Given that it's an internal verification system that fails when the assertion is incorrect, it could be helpful to at least throw a message in the output window when an assertion wasn't working

Would be great to have this as a PWA

Make them accessible in code with this: https://docs.microsoft.com/en-us/dotnet/api/system.environment.getenvironmentvariable.

In CodePen, you can show the HTML, CSS, and JS on one half of the iframe and the result on the other half, as well as open and close them by clicking on tabs located at the top of the iframe. It would be awesome if we could have the code be on one tab, and the console output on the other tab

Make it so that the code can not be altered, just viewed

There exists five redundant horizontal tabs 0x09 at the second line of all C# templates (Framework, Core, and Roslyn). They have existed for at least a year now.
I am hoping they can be removed.
Thanks.

Now that Blazor server-side has been released and client-side in preview (due to be released with .Net 5 in November), you should think about supporting the project type on .Net Fiddle

If you move the cursor to the opening tag highlight the closer tag

Any plans to support an Azure Function like interface with files area for run.csx, function.json?

Lots of C# developers out there who can't afford to have an Azure Tenant that can help collaborate on our projects.
