Chrome will include all that except the Opera part. Every user agent I've seen starts with Mozilla (the old Netscape), then Chromium-based browsers will mention khtml and Webkit, then Chrome, and after all that you get Opera.
(Khtml is a Linux rendering engine from the KDE project which Webkit/Safari and Blink/Chrome were based on.)
@Barkuti We have fixed user agent issue in our latest beta version: 59.0.2904.53502
Thanks for suggestion about bookmark. we do not promise any feature or improvement to user but we consider them in our planning.
@yeswap , right, I don't have a file manager. I dont really know that well this environment: it seems to only have a primitive viewer for Downloads. Thanks for the suggestion, I'll try this file manager you mentioned.
I guess Nawodit is probably pinpointing at one of those useless features of the Chrome browser. Useless, you hear me well. As a long time user of Chrome I always had smooth scrolling disabled, and it worked perfectly.
Not because something is implemented means it is good. Bear this in mind.
