Thanks for a great plugin wonderm00n. I'll watch for the update.
As for Plat SEO. I could have sworn it worked in the past. Having it pick up the critical tag is critical for FB shares etc as the tag is now always the same as the page/post name.
I only started noting this recently so while I can't be positive, I'm pretty certain it worked in the past.
All In One SEO is another popular one and I think they use similar method in tagging the title. They inset the title into the source of the page so I would think OG:Title would pick it up.
I believe without your plugin installed the title tag is used automatically on social shares. So maybe the solution is just to turn of OG:title if your plugin does not see it. That's what I was going to try.
Will report back.
