Well overall its a good effort so far and its only a preview so we cannot expect miracles. I hope it becomes a good browser but for now I am back on my Opera 28 all updated which runs like a dream. I am sick of people slagging the Opera browser off when I know most of them haven't even been using the newer versions and basing everything off Opera 15. People shouldn't open their mouths unless they test all the new versions of different browsers like I do. I've used them all PCXFireFox, LawlietFox, TeTe Atlier, Palemoon, Maxthon 4, Vivaldi, Liebao, 360, Slimjet, Sleipnir, Lunascape, Avant, IE11 and more. Right now Opera is head and shoulders above the rest. The bookmarks are a nuisance still but the actually bookmark system put in place works well and its clean etc. I think developers need to take a look at the customization of Maxthon and Slimjet and bring it altogether with maybe other actions. I watched a video by some lame brain who got so excited about the Vivaldi F2 menu showing tabs and the tab previews. This same guy slagged off Opera and I sensed he had never even seen an Opera with a preview since Opera has impressive previews on both the tab and side menus
Now as for the status bar, I personally hate these things because yet again they take up space on the screen. So it would be nice to have access on the main panel or menu to the same options shown on the status bar.
As for the removal of the tabs I could never use that feature as I have at least 30 and upwards tabs open at a time. But I think what is the point in removing tabs when you get no benefit from it such as the layout stays the same. What I mean is simply why don't the browser take advantage of the tabs being removed and give you a bit more web page viewing?
The idea of a pop-out video is another good option and ideally copied from the Maxthon 4 browser since you can pop out the video and pop it back without losing where you were. When you use Popvideo extension on Mozilla browsers you might be half way into a video and then pop-out that video only for it to start from the beginning. So as I say Maxthon 4 is the king of the pop-out video so copy their way of doing things.
I also hated the Vivaldi speed-dials showing up in the bookmarks panel, I ended up thinking it was an error and my bookmarks had somehow doubled so I deleted them and realized I'd deleted the speed-dials. Some kind of separation should be made or Ideally keep the Speed-Dials completely out of the bookmark area.
