Browse entire source repo, or create a branch, "at" a commit

One of the feature I think is missing in BitBucket Server is the ability to browse the source tree at a specific commit.

So I know the commit hash and I am viewing the modifications of that commit. What if I like to browse the repo at that time in the history?
Currently I have to click on "Source" navigation button and manually edit the url, because

/path/to/repo/browse?at=hash

works fine.

I would like to ask Atlassian to implement three simple helper features in the UI code:

1. (Taken from GitHub): if I enter the branch dropdown and enter a hash, be able to see the repository at that time of the history
2. A quick link to the above by the Commit view menu
3. Create a branch from a commit. I don't necessarily want to branch from another branch or a tag. Maybe I want to branch a specific commit. It's easy to do it locally and then pushing, easier to do it from the UI
