Thank you, Ven. Snowbird, for bringing this to our attention
This is precisely the feature I need for John’s pāli class where I share a homework-related translation in the thread before we’ve had the relevant class. That way I’m not giving away the answer, as they say. Delighted!
Oh, neat! Maybe you could mention it in class to let everyone know how it works. You can accomplish a similar thing with the Hide Details markup:
[details="Summary"]
This text will be hidden
[/details]
The big difference I see is that with spoilers you can do them inline like this. And that spoilers take up the same amount of space in a message whether they are hidden or not.
Also, you can type your text first and then select it and choose Blur Spoilers from the gear icon menu.
