It would be cool, when you could mark parts you want to destroy and destroy them with one click, because it costs much time and is annoying, when you have to destroy every single part alone

Removing the delay for scrapping parts is not the solution considering it just presents a UX issue. The proper solution imo would be to implement a scrap all button, or better yet, to get an "autoscrap below x rarity" function.
