commit graph
A level is you typing real Git commands and editing files while the commit graph moves under you, all on one screen. That needs a keyboard and room for three columns.
Open it on a laptop and you will be rebasing within the hour.
--soft moves the branch only. --mixed also resets the index, so your work stays but is unstaged. --hard resets all three and is the only one that can lose an edit. Everything else is recoverable.
Three panels, one loop. Nothing here can touch a real repository.
