Brave customization in new tab

hello! i was wondering if there is a way to customize the brave new tab system, like to add something to it ourselves or if there is some sort of plugin i can use to make it happen, like is there a way to customize it? and i have tried a styler plugin but it cant seem to be able to edit it in any way, would like to know if there is a way to do such thing! i asked because i assume as an open source browser its possible to change things here and there, and i just wanna add new widgets and other useful things to the brave new tab (like for example a todo list would be nice, some chrome extensions already do that by making your new tab a whole new thing)
