Here's an idea that would make Zettel unique and offer something that no other app does. I've tried many note apps, the vast majority of which are here https://www.noteapps.ca but I don't know of any app for Android where it's easy to multitask or work on more than one note at the same time, it's like every developer thought the same, that a person only needs to write new information, there are no easy solutions for those who need to transfer information from one or several notes to another or consult one note while writing another. My idea was for the app to have tabs like browsers, where in each tab it was possible to open a different note and switch between tabs to consult or edit the notes. The tabs would appear at the bottom of the top area, the existing icons would be moved a little higher to create space for the tabs, they would have the same behavior as in a browser, when starting the app the contents of the initial window would already appear in a tab, next to the tab there would be a + sign to create a new tab, the content of each new tab was always the initial window. Zettel would not be a note-taking app among many others, but an app that stood out for being the only one capable of easy multitasking.
