Feature Request : Neo Reader Favorites

Hello,

I use a boox Max Lumi to view my PDF paper collection. Very happy with it, I'm using the Neo Reader app. However I find it inconvenient to keep track of opened documents on the device. Neo Reader remembers the last 12 documents, I have to dig any older ones back from the busy hierarchy on my device. This system might make sense when you sequentially read books, but for my work I have to browse dozens of papers simultaneously.

Let me suggest the following solution :

Right now at the top left on the neo reader main page, there is a choice to either view the recently opened documents (clock icon) or browse the folder hierarchy (folder icon). It would be handy to have a third category : favorite or "pinned" documents you want to keep easily accessible. The user would choose documents they want to add or remove from this category using the context (tap&hold) menu.

I don't know if the below sketch conveys the idea but that feature would be terrific and really help people like me whose reading volume means they can't rely on the "recently opened" feature to keep track of things.

Best
