@alxgvr Vivaldi Bis? Tough nut to crack, even Vivaldi failed. I imported bookmarks from Opera and run thumbnails creation in directories one by one. Vivaldi failed. Hundreds/thousands (sub)pages to render in hiding (in backyard, not showing them) were processed thru several hours. Being more than happy (I felt lucky guy), seeing the bookmark thumb numbers diminishing in Status bar, I did open Speed Dial full of hope in the end. S**t! Vivaldi did nothing!
On the other hand, the more bookmarks, the traditional names and solid colors are more readable and usable.
Anyway it's up to you what you need to work with and last but not least, I do not think your request will see bright future. Opera development stagnated lately.
