I use VS Code or Sublime Text 3 (just syntax highlighting and command line compilation) but wish there was either a D based official editor (a la DrRacket for Racket or IDLE for Python, which are simple but good enough) and that somebody at JetBrains would adopt and maintain one of the Dlang plugins. I would even be okay with Walter Bright (or anyone in the D community) taking one of his Emacs implementations in D and giving it a GUI with menu options for people who don't know Emacs keybindings and letting the community take over, an officially supported editor would be healthy.
I almost exclusively code with JetBrains IDEs for almost every other language, especially Go. The way GoLand feels handcrafted for Go is phenomenal for me.
I've also used Spacemacs for D but Emacs is always hit or miss for me to setup Spacemacs so I gave up on Emacs, too much overhead, if I have to go beyond the install steps given by Spacemacs to make it work, it's not worth my time period.
