title: How to git stage changes in JetBrains IDE or similar functionality
body: <p>How to add files to git stage in JetBrains Rider? Is this feature implemented? If it's not implemented then in which window can I look through the staged files which I've staged using some external tool?</p>
  
  <p>[UPD]:
  The use case is to hold separately files I want to commit and files I don't want to commit at the particular moment. Stash is not the solution because I need all changes to be present. VS has this functionality and it's very convenient. You can stage and unstage any files with a single right mouse button click.</p>
