Moreover, since recently, a new tab does not open by clicking the mouse wheel. Also, previously, with a large number of tabs, closing by pressing the wheel forced the tabs on the right to move under the cursor position, which made it possible to close tabs in a row (because the size of the tabs did not change, they did not expand while the cursor was on them), now they immediately expand in an unpredictable way, so that at one moment the tabs on the left appear under the cursor, at another they behave as before, and at the third they do not determine their logic at all. Also, I can't say how, but the behavior of the new tab button has changed. It seems that it used to move along with the tabs being closed, which made it possible to open a new one immediately after closing the tabs. Now it remains on the right in place. Maybe it wasn't like I described before, but I feel some discomfort using this button after recent updates.
I'm sorry for my poor English.
