Rated 5 out of 5 stars

Simple to use. Works well.
v0.32 TB 45.4 on WIndows
However, the name of this addon is not great - 'pop' is a rather techy word, as is the allOneWordTitle. I found it from bugzilla. 'Expand mailing list recipients' would be better.
But thanks for maintaining this.

Thanks for 5 stars. :-)
If I remember right, I choose the name from the internal function I used... but I could try to rename it in future versions!
