come on, highlights are not missing, even more advanced, in /play you can highlight a square not only with red but also with blue, yellow and green, holding nothing or shift or control or alt, same about arrows. You can't do this in /live
Also there are emoticons, I do not use them though, but at least know they exist
so these features not only exist in /play but even far more advanced
There are some slight visual differences on those things
Yes. Those minute things can be differentiated especially when you use customized multicolour backgrounds with 'overlay' as your board (like mine) . The background I am using looks just amazing in /live than in /play. That's why I just mentioned this. Apart from this small difference, I am really happy with /play.
Thanks for your time
