Hello, I have three more requests: 1. Can I add a border around the thumbnails? like the red here: https://prnt.sc/n6870d but in black. 2. I would like also to change the size of the thumbnails, in my case I want them to be larger. 3. Furthermore, is it possible to add a title to each thumbnail? Something like this: https://prnt.sc/n68806 but on all thumbnails.
