I’ve done a couple of codeblock templates that can be one-click copied, but they’re not as prominent as the button in the 
icon. I do have a ‘poll guide’ on my list to do, but I’m not confident these people will read it. 
I do like to have the guides though, so I can link to them when it crops up rather than re-type the instructions.
The users of this particular site aren’t the most tech savvy, and will avoid any feature that seems ‘complicated’. If I can smooth some of the obvious pitfalls ‘automatically’ I think that would help.
I think the change in poll UI a while back made them a little less intuitive when it comes to the ‘single choice’ versus ‘multiple choice’, as people seem to think that ‘single choice’ means single option. So they pick ‘multiple’, and adjust the min/max to make it a single choice poll.
The ‘show who voted’ button is also a little tucked away at the bottom of the advanced options, when almost all of our polls would normally use it (apart from an occasional few admin ones).
But having a simple tweak to flip to ‘public=true’ as default would work really well for us (if I can figure out how to do it ). I’ve not thought of what I could do for the single vs multiple confusion, but if I can work out how to do the override, I may be able to do something about that too.
