Feature summary (what you would like to be able to do and where):

Allow users to customize the visual appearance of their Reading Lists in the app by adding custom thumbnails and banners, including images from articles or from their device gallery, along with layout options (e.g., grid on/off).

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
-Users currently create and manage Reading Lists, but they all have a standard visual appearance with no personalization options.
-There is no way to visually differentiate or organize lists beyond names and descriptions.
-Users who maintain multiple lists (e.g., topics like “Space,” “History,” etc.) may want a clearer visual identity for each list.
The user expects to:
-Edit a reading list and access a redesigned “Edit reading list” interface.
-Add or modify a banner image and thumbnail preview.
-Choose images either from:
*Existing articles within the list (with search and selection options), or
*Their device gallery.
-Toggle layout options such as enabling/disabling a grid view.
-Adjust thumbnail behavior depending on layout (e.g., single thumbnail when grid is off, multiple when on).

lack of visual customization and differentiation for Reading Lists, limiting organization and personal engagement.
