I guess I could probably use MS Visual studio as an external editor and get some of those functions, but I don't want the massive bloat that installing VS would cause
VIsual Studio Community (free) with Visual Micro (free, and low cost optional software debug)... in my opinion having tried all the IDEs, is the best. Visual Micro is a plugin that allows Arduino-style pre-compilation.
So VS+VM is like a great editor with the full IDE for multiple serial monitors concurrently and support for the popular downloaders.
Also support for GCC ARM for STM32, Freescale, ESP8266, etc.
VS+VM is much better than Atmel Studio, IMO, for what we do.
With today's big disks and big RAM, big IDEs isn't an issue for me. VS+VM is very, very fast on my PC with its 500GB SSD. "Bloat" isn't an issue at all.
Most of my non-work-in-progress files are on my NAS.
