I often need to edit config files (MySQL, PHP, Apache, ...) in directories like C:\Program Files that require administrative rights. When you open them with code and save the file it says "Permission denied". So I have to run Code with right click as administrator and then choose "open file" to open the file. Once, it is not possible to simply drag&drop the file into the elevated Code. The other problem is, once I already have code instance running without elevated rights (say I have my project open and now I need to edit a config) I cannot get another instance with elevated permissions. UAC asks for permissions and a new Code window opens, but it is not elevated, when I save it says permission denied. I have to close my project before I can get an elevated Code instance.

I don't know if that is a restriction of Windows but seeing that you can, for example, run a normal Powershell and an elevated Powershell side-by-side I think this should be possible. The optimal case of course would be if Code could elevate itself if it can't save a file because of insufficient permissions. But being able to run elevated and non-elevated side-by-side would already help a lot.
