[Feature] Display flag key in UI

[cszczepaniak]

Flag keys can be changed from the generated key to have a descriptive name. It would be nice to show the key in the UI.

Expected Behavior

Flag key should be displayed next to description.

Current Behavior

Flag key is not shown in the list of flags. Only description is shown.

Happy to do this work if you think it's worth adding.
