Since 2019, they've made Opera slow, unfunctional, unintuitive, redundant, uncustomizable, etc.

-> There should always be a space between tabs (important when you have a large number of tabs in a single/same window). Tabs shouldn't be mixed and overlapped, and tab icons/logos should be hidden.

-> Opera's home tab (Quick Access - Home Page) counts as another window. This means that when the browser (including all windows, the Opera process) is closed, whether due to a crash, a restart, or an update, the blank home/quick access tabs shouldn't disappear or close (I use these tabs as a way to separate tabs, and they're useful).

-> The feature to highlight/underline duplicate/repeated tabs (tabs with identical URLs) becomes useless/ineffective because when you hover over them (without clicking on the tab), the tab name/title is displayed too high (too high). The box has to appear *below the height of the tab bar, i.e. below the tabs because it covers the "duplicate page" mark/signal.

-> If the user doesn't want to use the "Island" feature at all, it's nothing. I mean, if I have "islands" disabled, when I move/scroll a tab in the tab bar and want to place it in front of or behind another tab (especially when there are a large number of tabs open and they are very close together), it doesn't have to merge/join any tabs; they have to repel each other. You know what I'm saying, it's a pain to undo "islands" if I don't want that feature.

-> The sensation of pointer speed and shading when scrolling between tabs, the speed of clicking and unclicking tabs, and the overall speed of the browser interface have become very slow and sluggish—too slow, and it makes you work/function slower and clumsier. Of course, Opera has become super heavy and not optimized at all.

-> The width of the active tab* (the selected tab being displayed) in the tab bar should always*/permanently* (regardless of the number of tabs in a window) be at least 60 pixels, or a medium size, which makes it easy to accidentally hit the close button.

-> Add a "trash can" button/icon to the right of the tab bar (where the "search tabs" button is) with closed tabs, and without setting a limit of up to 10 last closed tabs. Don't tell me that's what the history is for, because the history doesn't show you the tabs in their closing order. The history shows you the tabs in their creation order, and that has nothing to do with it. The trash can only shows the closing order, but don't limit the trash can to just 10 tabs... (it seems done on purpose).

-> Every minute that passes, Opera consumes more memory and system resources and is slower, it's getting worse. Focus on loading tabs much faster and using less memory; 95% of all new "stuff" additions are unused.

Minor extra:

• The purpose and strength of the "pin tab" feature is to make it difficult to close for any reason. So, an extra security step must be added to be able to close a pinned tab, such as: To close a pinned tab, the "close tab" option does not appear when right-clicking on that tab. 1. It requires/needs to "unpin/release tab" and then/2. The "close tab" button appears.

• The "click to open new tab" button should take up the height of the tab bar and be square-shaped and not so small. Now it's a tiny pea, and you have to be absolutely precise (and slow*) to open a new tab. God.

• You've made the shortcuts, the boxes/cells transparent... depending on the background/wallpaper, neither the title/name nor the shortcut logo can be seen (and keep in mind that many users use a blue light filter to darken and change the screen tone to reddish, etc.).

• The "squares/window" logo on the "Quick Access" tab should be all white/filled, not just the frame and the inside black.

• All the icons displayed in the browser (especially the address bar) can be removed if desired (because most of them are either unused or useless).
