You'd like the site to have an option to switch between light/dark theme, right? Or a middle ground, like a dark blue/purple background? I like dark mode because it doesn't strain my eyes too much (and I still don't wear glasses). That white #ffffff is harmful to our eyes (although it's not the only one that emits blue light).

About the notification informing the temporary unavailability of NO AML mode, I didn't find it annoying. Maybe a "don't show again" checkbox might be a good addition, but that would require storing cache (I don't remember if SageSwap keeps caches - I believe they don't keep it).

If I may suggest one thing.
After creating the order, clicking on the letter of guarantee opens in the same window. Wouldn't it be better if it opened in a new window/browser tab, and the order page remained active on the client side?
It may not seem like a big deal, but I know that users like to stay in the order page until it is completed. In the end, it's just adding the _blank tag.

It will be better, because I think in some platforms, it will automatically download once you click on the letter of guarantee so that you will automatically have a copy. But this isn’t a big deal in my opinion, and your suggestion is a good one because some people might be distracted, but still I think that, since it didn’t stop the swap from going through, I think one can decide to open it in another tab to avoid distraction from your swap.
