From 9ff2033e936689135210989a5fee057a4a13527e Mon Sep 17 00:00:00 2001 From: Miquel Sabaté Solà Date: Thu, 13 Mar 2025 22:52:49 +0100 Subject: Add a title and a main screens MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds the skeleton for having a title and a main screen. For now the title menu doesn't do much, as the selection is simply ignored, but at least it already knows how to cycle between these two states.
