Hello,
The delete & reset feature (Vanadium settings –> Site settings –> All sites) doesn't forget the custom zoom level that can be set per-site from the three-dot menu. The only way I can see to do it is to open the site again and change its per-site zoom to the same value as the global zoom setting (Vanadium settings –> Accessibility). This might be a privacy issue (I'm unsure), but regardless, I don't like the fact that forgetting a site's settings/cookies/offline data doesn't forget all settings for it cleanly.
Thank you
