Yes, please! I would like to see a draggable scroll bar in Vivaldi Android. Sleipnir has it, Opera I heard has it, Samsung Internet has it as well. The best implementation is Sleipnir though since you can drag anywhere on the right side and it takes you there and you can keep dragging to scroll (similar to Windows).
Of course, this is to be a setting as perhaps not everyone wants this.
This is very important for quick navigation as it's tedious swiping up or down on long pages.
Firefox has rudimentary themeing where you can apply an image / texture as a background on the main toolbar. It would be nice if vivaldi could plug into this, then they could have access to that whole library from the get go. If not, simple choosing of icon bg/fg colours would suffice.
@yashpalgoyal1304 It has been a feature for the all versions of Firefox (Android) in the recent past. It works like so: https://support.mozilla.org/en-US/kb/open-links-background-later-viewing-firefox-android
It's a wonderful feature when you're using news aggregators, etc. where you want to read multiple links, and open all those links in tabs without having to continuously switch between the browser and the other app.
