Simply put, the address auto compeletion does not work very well in Vivaldi.
What I want is like what Google has/is doing and what some browsers used to do. Even if I have never before typed in address, I want the auto complete function to be hinting me with web addresses. Like if type "goo" the address I need is already there for "google.com.
Then with addresses that have been entered already the auto complete should be hinting me with the shortest address possible which is the website address such as "google.com" NOT "https://www.google.com/search?q=old navy boise towne square". Hinting the website address is way better, because most of my searches any way I need to start back at the home page to search or something like that. The only way that website home pages are correctly hinted is by typing them in "completely" anytime I want that address to pop up later. For example to get pinterest.com to show up when I later type in "pint" I have to have typed that address in earlier as "pinterest.com".
@LorenzoPearsono: This is a couple of different issues. One is search engine search suggestion issues in the address bar. The other is the URL autocomplete design within the address bar itself. Vivaldi can't afford the fees right now to ship with some search suggest URLs built in, but any user is allowed to input these on their own -
for instance the search suggest URLs for various engines are:
Google Images: https://www.google.com/complete/search?hl=ru&ds=i&output=firefox&q=%s
Now as to the addressbar's preference for which of several URLs to autocomplete, you have to make sure that in
settings/address bar, you have suggestions enabled, "always prefer bookmarks" disabled/enabled as you prefer, etc.
AND THEN, Vivaldi had the addressbar autocomplete largely sorted, and then the intake of a Chromium version broke it again, and so they are working on sorting it once again. It's almost certain to be better in the next Stable. It's already at least a little better in the recent snapshots.
This is what make me really angry when using Vivaldi. Autocomplete added a long way to the url, not just a domain. And there was such a simple set-up and everything is in order. This should be disabled by default.
To remind - open the preferences (Alt + P), type Autocomplete in search bar and deselect "always prefer bookmarks" (second item).
