This is an alternative top menu to categorize plugin menu items as you wish. Using this plugin doesn't change the behaviour of the existing top menu.
- Assign a gesture to trigger the launcher quickly
- Create top menu items (with icons) and add plugin menu items in them
- To use your custom icons, place them into the koreader/icons folder
You can download the plugin from this repo:
