Pity people who post extensions on Github don’t simply include a link to their example MakeCode so that the program downloads to our browser including the extension. The “test.ts” on the Github above does not include an extension and your link, as an extension search cannot be found by MakeCode. I thought the whole point of “share” in MakeCode was so a naive user (student) could click on the link and see the completed example program in their browser with the extension included.
