Yep, gotta figure out how to do that .. I tried a few designs but it didn't feel right. I really don't want to do what Twitter did..

Have you considered long press on a note could pop up a menu?
Currently most other apps like a web browser long press lets you select substring for copy & paste. That isn't needed anymore with Android 13+ clipboard because it lets you select a substring from the clipboard after a larger amount of text is copied. Thus Amethyst could use long press for a different purpose.
BTW could you please add the Translate toggle on every note? Perhaps in the right context menu. I currently have no way of requesting a translation of Japanese posts while I have the Japanese keyboard installed. I want to toggle translations on and off per post. That is helpful in language learning.
BTW why is the right context menu button missing when you zoom into a particular note? Perhaps long press could be the alternative way of calling for that menu?
