A spoiler button just like the img button in the "New Post/Thread" area that generates the [img] code but for spoilers that generates the [spoiler] code

I mean, it would be nice, but I don't think it's worth the effort.

When we upgrade to the MyBB 1.8x branch I believe they made it easier to accomplish such changes.

This was Omniscient's last response to this suggestion, I believe it would still be current.

The editor requires core edits. Omni won't change it until we upgrade.

It's sort of stupid. Not the suggestion, but this version of mybb. Editing or making a new button should be easy, and not require core edits. (Obviously not ranting on HF but on myBB)
