Hello Sigil community,

I am using a plugin (Template2) to open eBook templates. In Sigil 2.4.2 and earlier, when I opened a template using the plugin, the "Save As" dialog would automatically suggest the template/plugin name (e.g., "Template2_.epub") as the default filename.

Since Sigil 2.6.0, however, the save dialog always shows "untitled" as the default, even though the tab title correctly displays the template/plugin name.

Steps to reproduce:
1. Install the Template2 plugin (or any similar plugin that opens a template and sets a book name).
2. Open a template using the plugin.
3. Observe that the tab shows the correct name (e.g., "bald_").
4. Click "Save As" for the first time.
5. The suggested filename is "untitled" instead of the plugin-specified name.

Expected behavior:
- The save dialog should suggest the plugin/template filename as default, like in Sigil 2.4.2.

Actual behavior:
- The save dialog ignores the plugin name and shows "untitled".

Is there a way to force Sigil 2.6.0 to use the plugin-specified filename for the initial save, or is this no longer possible with the current version?

Thank you for your advice!
