In chrome, you can ctrl click each tab or shift click a group of tabs like in opera, but you can drag them between windows. I need this feature to go full time to opera as it seriously hinders my productivity. Thanks

Over the past 24 hours I have tried to make my switch over to opera gx. After setting everything up and transferring all my extensions and profile setups over to opera, I found 2 things that annoy me. I can't drag multiple tabs at once. In chrome, I constantly use the shift click tab and drag feature as I have multiple monitors. The other thing that has stopped me from my transition is the chrome cast feature. I have googled and found that opera use to have cast and no longer does. Any ways to do these things on opera? To recap, multiple tabs moving between windows and casting on opera. Anyone know work arounds for these? Thanks in advance.
