Can I export only a single subtree?
If you want to export a subtree, mark the subtree as region and then export. Marking can be done with C-c @ C-x C-x, for example. Alternatively, you can select option 1 in the org export dispatcher (e.g.., C-c C-e 1 h to export the current subtree to html). By default, the title of the exported file will be set to the heading of the subtree. You can, however, customize the title and other export options.
