Set your own template for Atom's title bar. Uses underscore.js templates.
The following variables are available:
projectPathprojectNamefilePathrelativeFilePathfileNamegitHeadgitAddedgitDeleteddevModesafeMode(always false, since the package will not be loaded in safe mode!)
Plus the atom global, as usual.
The default template matches the regular Atom titlebar:
<%= fileName %><% if (projectPath) { %> - <%= projectPath %><% } %>
<%= fileName %><% if (projectPath) { %> - <%= projectPath %><% } %> - Atom <%= atom.getVersion() %>
<%= fileName %><% if (projectPath) { %> - <%= projectPath %><% if (gitHead) { %> [<%= gitHead %>]<% } %><% } %>
