I'm new to opera, I've never been to facebook (don't have an account) but like everyone else messenger keeps adding itself back to my sidebar. Not expecting a fix just adding to the list of people who are having this happen, will be switching browsers if it keeps happening.
@sgunhouse I feel that @ant8672 brings up quite a few valid points. With how customizable the browser already is these would all be features I'd be definitely looking forward to seeing.
Sure, this is a bit of a late reply but again, these would all be extremely useful tools and would give Opera GX quite an upgrade in customizability as well as popularity. Especially that Easy Setup bar, there is definitely no use in having it after you have already set up the browser since you have a sidebar and loads of keyboard shortcuts and an entire settings page that does what Easy Setup already does.
