Bigme Inknote Color Lite, alternative note-taking app

[foreverconfused]

So, the built-in note-taking app for Bigme Inknote Color Lite is lacking. This is even considering my limited expectations from it. I want to be able to create notes in different folders and be able to move, import/export them. In the built-in app. You can export, but cannot import it back. You can check/select notes to move/export them, but you cannot check/select a folder. Is there a free app that could fulfill these features? Regarding note-taking, my expectations are simple. I want it to have mostly basic features, drawing, erasing and setting a background (like 5mm square ruled paper)

Any suggestions are welcome.
