Affected part of DeckDeckGo

• Studio (online editor)

Feature Description

Add an option to "archive" templates in the editor.

• In the templates settings page, add an option, on each template, to "archive" it

• The information "archived" should be persisted in the database aka should be added to the template.ts model

• When the user want to add a slide, in his/her list of templates those which are archived should not be listed

Use Case

We cannot delete templates because if we do so, the slides which would have been created with these would not be loaded anymore aka if use open a deck in which such templates where use, the related slides are going to be empty.

Open question

In the settings templates page, should we add a filter to find archived template? should we also add an option re-activate? If "archived" is handled through a checkbox in the detail modal, this would be solved.
