Alternatives
Need Updated version!
Jon Stephenson von Tetzchner tried to fulfill that wish by developing Vivaldi surfing app.
In terms of features, none can beat Vivaldi web app so far.
It can do a lot of things without having to resort to extensions.
Pick one that suits your taste the best or create your own color mix to make it more personal.
Change the theme of the Private window as well if you feel necessary.
The most intriguing part is the option to schedule themes based on time.
Sidebar
Not every web app has a useful sidebar like the one existing in Vivaldi web app.
It is more than just a place for bookmarks and browsing history.
The most useful panel, though, is the one that lets you collect information from web pages.
Lets say you find an interesting quote.
Highlight the quote, drag it to the Notes panel, and it will be saved as a note.
Status Bar
The status bar is as useful as the sidebar.
Need to capture a whole page or just a part of it?
The tool to do the capture is there.
Among the available options in the status bar, the best of all is to block image animations.
Many dislike them, yet they are everywhere.
The softer approach to the animations is the option to play them only once.
Hit the Page Tiling button in the status bar and choose a tiling modevertical, horizontal, or grid.
Thats all you gotta do.
No need to search and install any extension.
All in all, Vivaldi surfing app is simply the best when it comes to customization.
