I use it occasionally as a heads-up about tricky functionality, or to point out something that should be read by future developers, so yes, like a warning. It's similar to `NOTE`, but more important. There's nothing to be done, so `TODO` wouldn't make sense.

Why not `IMPORTANT:`?

I haven't seen `XXX:` anywhere, but it's immediately disconcerting as the icon is meaningless. If I have to reach-out to you to discover the meaning of some word you use, it's a bad word.

> Why not `IMPORTANT:`?

Like others mentioned, it's not as an established convention as `XXX`. And it's much shorter and quicker to type, particularly convenient when you just want to rant about something, which is the usual use case for `XXX`. ;)

At the end of the day, these labels are meaningless unless the entire team is following the same conventions. So using whatever your team agrees with using is the most important thing.

Does it really need to be something more important than NOTE? If you are working on the code you should be reading that NOTE anyways, so why not use a word with more specific meaning? Or even just IMPORTANT. Before this thread I would have never known what XXX meant, having never seen it before.

I suppose if its defined somewhere as a standard for everyone working on the code it may make sense. Just doesn't feel very intuitive to me.
