Windows offers the option to stop using the Windows Recycle Bin and to have items deleted immediately. Maybe such option would also be a good solution for Opera's handling of deleted bookmarks. Anything coming out of the trash on its own, [...] could also be the idea for a nice trash movie by "The Asylum", I think.

We're about to enter 2019, and dark theme/skin is still the same, no improvement. -download page -history page -bookmark page -extension page -setting page -the menu -right click menu -in speed dial the folder are still in white... Remaining items above still mismatch with dark theme which is possible to solve, I think so. Why dev don't really bother to do anything about that?
