@palocx Regarding 4 (icon colour) you can use Vivaldi Theme to change the colour of the Address Bar/Extension field to something else. Also can choose whether it changes depending on Web Site (Accent Colour).
I don't know of a layout description for Vivaldi - but it is the same terminology for all browsers (I believe). Maybe there is one on Wiki etc??
Not sure what you mean by Google Marketing; but as Vivaldi is a "new" browser not all sites will have been updated to recognise it (although I'm not sure why they would need to, I thought checking browser names had died out years ago).
Also, Vivaldi uses the same engine as Google Chrome and Opera, so simple checking may get it wrong !
So just what is there to stop Vivaldi from doing the same. In addition there are sites that ban that and would probably just ban a browser with it builtin.
The OS or even the hardware could do so too. You never can be sure but you can shrink the probability, reduce the amount and have some control how your data is handeld.
So even if Vivaldi do so, I trust it more than the creator of the Add-on. My data would be in a larger database, more anonymous and used with more restrictions (laws).
And sites which ban that you simply can't visit anymore. If all do so, they need to allow it again.
The same for the edit pencil and delete minus symbol in the bookmark panel. It's to easy to delete a bookmark or even an entire folder and sub-contents. Yes, the trash can saves them, but it should not be possible to make simple mistakes. The possibility for large loss of bookmarks exists.
autocomplete: is too aggressive. even when bookmarks aren’t favored, I type in one url and am sent to a completely different website with similar words (ex: play.google.com/store vs play.pocketcasts.com). I must also backspace to shorten a url i’ve visited before to get to the main page of a site when I should tab to complete a longer one, expanded in a light opacity.
i can only stress this point - i type "youtube" and autocomplete fills the line with some url from history or bookmarks - even when i shorten it, vivaldi would never take me to the homepage.
We changed the structure of features requests and will make a topic for each release (1.4 then 1.5 then 1.6 etc) that way it's easier for everyone to follow it up. For that reason we're closing this thread. Please visit the appropriate topic to submit your new request.
Thank you for your understanding and sharing your great ideas. We appreciate them greatly.
It was the great Idea, that way you see what is priority on each moment too
