Adding indicator near the page number on the thumbnails view

[user67]

I’m trying to apply some business related logic to the thumbnails view as shown in the screenshot and I’d like to know if there is some sort of api that allows me to access the process of generating those images.

Hey there,

We do not expose any APIs that can do what you’re looking for here. However, our UI is open source meaning you can clone the code and make any customizations you wish.

We have a guide on that here.

Thanks!
Logan
