You can already get Sigil to inject end tags (check out the Sigil menus). Direct html editing is direct html editing. If you want to edit in PageEdit then do so. But be prepared to fix up the generated html to make good code.

Also feel free to use Sigil's "open with" capability to use the html editor of your choice.

Please note: neither old or New Sigil / PageEditare meant to write your book with. That should be done with a real word processor (like LibreOffice or Word) and the resulting html imported via a plugin into Sigil for cleanup, adding special features, building the toc, etc. PageEfit itself is meant for proof-reading and small editing.

So use a real wordprocessor to create your book content before using Sigil.
