FSE: no (clear?) way to rename or delete template parts

[Nic-Sevic]

Steps to Reproduce

1. create a new template part
2. go to templates menu and try to rename or delete
3. Doesn't seem to be an option for either

What I expected to happen

You should be able to click on the template part and be able to edit it either in the editor or via a submenu

What actually happened

clicking the template part opens it for internal editing but I couldn't find a way to delete duplicate parts I created by accident or to rename them if I failed to name them on creation

Template Parts can be edited/deleted/renamed directly from WP Admin - so I'm uncertain of the need to be able to do it from within the Site Editor.

@annezazu Is this something that is likely to differ between the Core implementation and what we do on WPCOM?

[annezazu]

I do not see a reason for why this would differ but would have to check with WPCOM product folks. For now, I do want to note one outstanding issue related to the name change properly propagating (that's the only issue I've found related to this): WordPress/gutenberg#29844

Renaming

It's possible to rename a template part through the block settings menu, although as @annezazu pointed out, the name change doesn't propagate throughout the UI without a page refresh.

Something to note -- a template part block has to be selected in order for this option to appear in the block settings menu. This means that if we select a template part from the navigation sidebar and open the isolated template part view (as shown below), we won't be able to change the template part name.

Deleting

As far as I know, template parts can only be deleted from the template parts list page accessible through the wp admin dashboard (Appearance > Template Parts).

@Addison-Stavlo I know you've worked a lot more with the template part flows than I have. These UI requests make sense to me, and it feels worthwhile to bring this up in core Gutenberg. Wondering if you have any thoughts on the matter.

These features have also been requested in the past.

I think the interface is in a bit of redesign currently, so I don't have much of an opinion here. But the navigation sidebar noted above has recently been removed in core so this flow to manage template parts from it doesn't really exist in this form. There is an 'isolated' mode you can load a template part in, and the mentioned sidebar on the right seems like a logical place to have controls for that. There may be some contexts where deleting may or may not make sense and that control may have to be conditional. 🤷‍♀️

Im sure @jameskoster and other core designers have thought about this a bit more, and have a better idea where this may go in the future.
