I am here:
I want to go back to "test works", but if I click "reset current branch to here" over the "test works" commit, no matter what I choose (Soft/Mixed/Hard), it removes (deletes, erases) the "not sure about this direction..." commit. I don't want to delete it, as I may decide to get back to it later, I want to create a branch from "test works" and try another direction, and only then decide.
I know I can create another "branch", like this:
but it forces me to add another branch. Is there any way I can get to the following state?
(where the top-of-the-tree (aka "HEAD"?) has no branch)
I prefer only Git-Extension point-and-click GUI actions, if there's a way to accomplish it that way.
You won't be able (well, you could but it won't be of any use really) to rewind your branch and leave the latest revision un-referenced. The proper way of doing it would be to use another branch and let that represent the new direction of your development.
I would right-click the revision known by its comment "test works" and create a new branch from there.
