 ### Added
+- support adding untracked file/folder to `.gitignore` ([#44](https://github.com/extrawurst/gitui/issues/44))
 - support reverse tabbing using shift+tab ([#92](https://github.com/extrawurst/gitui/issues/92))
 - switch to using cmd line args instead of `ENV` (`-l` for logging and `--version`) **please convert your GITUI_LOGGING usage** [[@shenek](https://github.com/shenek)] ([#88](https://github.com/extrawurst/gitui/issues/88))
 - added missing LICENSE.md files in sub-crates [[@ignatenkobrain](https://github.com/ignatenkobrain)] ([#94](https://github.com/extrawurst/gitui/pull/94))
