About Floating Browser,
At "Identify as Desktop (PC Mode)" Browser must remember last chosen tick to launch and run every WEBSITE based PC Mode, but currently The browser forget last chosen tick(Identity as Desktop) so after closing the browser and relaunch it at next time it forget chosen Identity as Desktop option and all bookmarks running at mobile mode, for example if u bookmarked Google translate at "Identify as Desktop" then it would saved as "https://translate.google.com" but after closing browser and next startingup the browser if u click on bookmarked Google translate page, then u will see it will run at Mobile mode that is https://translate.google.com/m/translate, my mean is The Browser support remembering last chosen "Identity as Desktop" option Generally or preferably remember last chosen for each webpage, Can u!?
