I posted this on reddit originally, but then saw you had your own forum thingy, so heres a copy:
Hi, I just started using Opera GX. So far I like it. However I have a few requests/comments.
-Bookmarking: If I click on the bookmark icon (the heart at the top of the bar) it fills in colour to mark that the page is bookmarked. Please allow me to click it again to unbookmark a page. Right now you have to go into bookmarks and delete it there instead of just clicking the icon at the top.
Sidebar: I like the functions it has. However I don't like that its just sitting there. Please give an option that makes it auto hide or something. Or possibly shows itself by clicking the Opera logo top left. Alternatively, let me move it to either top or right side of the window. Right now its either show on the left side or don't show at all and go into the settings to enable it again.
Force dark pages: Cool function and it seems to work well. However, some sites I go to I like them not to be darkmode. Right now I can turn the whole thing off and on in the settings. Would it be possible to show an optional button on the top right where I can turn off/on force darkmode for ease of use.
Moving a tab to my other screen opens that tab correctly. However I've noticed that moving it back into an open browser does put the tab in correctly. However it leaves behind an empty browser window on the GX corner page, instead of closing the window since I dragged the only open tab into an already active window of opera GX.
I'd like the option to remove/hide some of the icons at the top right. (Example: pinboards, send to myflow, snapshot)
