I completely agree with your caution about action tags, @isabellelauren.
"I am so fed up with this," she frowned.
This is not correct use of an action tag.
She frowned. "I'm so fed up with this."

Thank you for your comment. ;-)
Matching the action with the appropriate speaker is definitely essential also. It's one of those things we help people with a lot in the Fiction Workshop--making sure the speaker is clear enough. The main thing is, as Tiny made clear in her article, that actions are not dialogue tags and have to be formatted as sentences, not attached as tags.
