I've spent a couple of hours adding a new feature tonight. You can now click to reveal solutions within comments. It should handle the variations 1a / 1A / 1across / 1ACROSS. This has been included on a trial basis, please do let me know if it's not working how you expect and what you think about it.
Now that I've used the feature a bit, I feel that not being able to see the clue numbers after the switch is somewhat annoying. Question being, would people prefer to ability to toggle back or shall I just add some hover text to each solution that displays its number?
@laccaria that's fair enough. Like I said, it's there on a trial basis for now. I was hopeful that having the solutions shown on click rather than hover might have been enough to prevent spoilers. I'll add some code tonight to allow the solutions to be toggled and see what people make of it.
You can now toggle the solutions on and off.
