Faster "Find As You Type" in Bookmarks
I imported lot of bookmarks. When I type sth in filter field, list is filtered. But when you have lot of bookmarks, pressing next key with next letter should interrupt filtering, because waiting for filter big list feels slow. I think that simply check that next key is pressed and interrupt present filtering will be faster and more pleasant. As worse alternative - button for disable FAYT which enables bookmark filtering after Enter key.
After typing a mere single character in search in bookmarks panel or in the Quick Commands dialog box (f2), Vivaldi basically comes to a stand-still for several seconds here. I hope this is a known problem and will be resolved.
