Hide commits from specific users (e.g. bots)

Since switching to GitHub CI, in our multi-repo environment, package versions are kept updated via an automatic process, a bot user updates the `package.json` whenever a dependency has a new published version.

While this is very comfortable, it clearly pollutes the history (see attached image). Hiding branches does not work here as these commits are on the `master` branch.

It would be very nice to enable to mark some users (e.g. bots who create auto-commits) and have their commits visually removed from the graph (maybe with some extra graphics added, like ... to know that something is hidden).
