Thanks to point the cons / reasons it was removed so I don't have to do so.
I was about to say the same, but I thought:
What about calling it "Something else"?
Like "Add a marker" or something. It will add a nice "Marker added", maybe with a cool yellow/cream background, and automatically scroll so it will be the first item on the window.
For sure, you can scroll back to see the rest of the history and stuff.
Now I'm wondering I just wrote the same thing you did.
I bet Rick's answer will be "I understand this is totally useful, but it's a v4.0 level of / low priority feature". :wink:
Changing your thread title is highly recommended.
One more thing: if this feature will be implemented, ability to name/rename the marker will be totally kool.
