Congrats to Vivaldi for publishing the mobile browser. Here is my little wishlist of what I consider missing features.
In addition to Reader view, it would be nice to have themes (to theme the web rather than the app) or the Page Actions menu with Filter Grayscale, Filter Invert, Fonts Monospace and other items great to have on handhelds.
As to tab management, the tabs bar in the tablet version should be hideable, and the tabs window is painfully missing a long press function. The long press on a tile should either open a menu (to e.g. clone the tile) or start multi-selection (for bulk-close, bulk-bookmark, etc.).
In the tab management window, the app menu should have the option for list view instead of tile view. As to the tile view, it would be nice to have more tiling like on desktop Vivaldi, with barely any margins between the tiles so as tyo make as efficient use of the limited space as possible, with dragging of content, dragging of tile edges, and drag-and-drop of tiles.
And something I would like to see in every browser: Make the device’s volume buttons scroll webpages, a setting for both full-page and half-page length.
I know, never going to happen, but just a few suggestions to make Vivaldi mobile version unique.
