Good requests, a lot of these have bothered me too at some point. Most of these are editor features/issues, so you can also report them on the Editor 2 issue tracker so the team can track them easier.
- 2 is a “high priority bugfix” on the latest roadmap, so there’s some hope for that.
- 7 is fixed in Editor 2.
- 9 is fixed in Editor 2.
- 10 is fixed in Editor 2, honestly it’s one of the main reasons I use Editor 2 as much as possible.
- 12 - Do you mean the built-in text editor? If so, this is fixed in Editor 2. (it also works fine with Atom)
