Add a feature that lets speed dial wallpapers change periodically such as every time a new speed dial tab is opened or every 1 hours/ 1 days, etc. We already got the daily wallpaper feature which is a nice addition but does not allow users to choose which wallpapers to cycle through and instead only allows the stock opera wallpapers, simply adding the option to pick between a pool of wallpapers will add a ton more customisation and personalisation options. A lot of users like customizing their setup and this saves us from manually swapping wallpapers every time. Its small but it adds a lot of quality to the user experience. This would make opera gx feel even more unique compared to other browsers as almost no browser has this feature.
