Hi Michael,
We’ve seen a couple of those plugins, and we take some different approaches with Draw Attention. I think most choices work out for the better, but unfortunately it means it doesn’t work as a frontend editor. Ultimately we will have more flexibility in the admin to build out more features and support a wider variety of WordPress themes this way. There are always tradeoffs :/
We have added several actions and filters to the code (and we accept and consider suggestions if you have a spot that needs an additional filter). We don’t have a great centralized list of them all at the moment, but let us know if you have any questions on the ones you find within the code!
Thanks,
Nathan
