Notice: when you make tabs closable like this:
toolWindow = ToolWindowManager.getInstance(project).registerToolWindow("Code Time Machine ", true/*Can close tabs?*/, ToolWindowAnchor.RIGHT);
or
ttm_content.setCloseable(false);
you should also handle the close event in order to remove file from Sync button.
