SmartGit already saves its settings as files (in its settings directory - see the about dialog for its location). You may create a repository for this directory on your own.

Aurelijus, please try the Vivacious-unity-zblackout-aqua dark theme.

This is a context menu that contains menu items that can operate on the selected files. Stash does not operate on selected files, but always on the whole repository. Hence I voted against this request.

Mark your repository as favorite. This will automatically fetch the latest changes.

The Output window is just that: the output display. If you want to use a command line, you can open one from the repository's context menu.

Maybe you misunderstood. In the SmartGit preferences you can configure the sync-order - either push, then pull or pull, then push.
