Drag'n'Drop files to browser window [Feature Request]
When you drop file into browser window, it opens in new tab like document or something, regarding to its format/extension/etc. Like in Firefox.
For example, when you drop .html file, it opens like local web-page.
You might want to post your request in the following thread: https://forum.vivaldi.net/topic/13217/feature-requests-for-1-7/302
You can upvote ideas you like and the same can be done with your request.
I did a short check for you and it seems that there are already a few drag & drop requests but only regarding bookmarks so yours would be the first for general data drag & drop (as far as I have seen it)
@zaibon Okay, thanks for answering!
