I can't see whats wrong on this approach.
What's wrong is you cannot use the other many search engines directly in the address bar using a keyword, like you can in Opera 12 and Firefox.
That is a must-have for Vivaldi.
One can agree, but this problem is unrelated with the "search box, yes/no" thing…
Until the issue is fixed in Vivaldi, you can easily overcome the problem in a number of ways:
#1 changing the default path of the downloads folder (just right click on it and move the folder on the desired path)
#2 using the symbolic links. Its the Unix way. But that can be used on windows too, unfortunately the latter lacks a way to do it graphically
Btw you can use this http://schinagl.priv.at/nt/hardlinkshellext/linkshellextension.html to manage (and understand) them easily.
#3 you can just resize the partitions of your HDD to meet better your needs, with the integrated OS tools, or with a lot of partiton management programs
Hey, I had the same problem, after a few attempts of redownloading and trying different locations I tried manually extracting the files and it works.
So get 7zip if you don't have it, install it, rightclick Vivaldi_TP2_22.214.171.124.exe and from the context menu choose to extract it wherever you want to extract it to. (Or open it with 7zip in any way you prefer.) You will then end up with a Vivaldi.7z file which you can extract the same way again and it contains all the files and folder structure you need to run Vivaldi.
most of the things you would want to do via the context menu sound pretty hard to actually implement, because webpages are structured differently than how you select.
Imagine a website that just has a left and a right column (both having items therein) and you select a rectangle across both in the middle of the page.
