What was the standard compiler for A2000 back in the day? Certainly it had a compiler available for purchase?
It was called Lattice C, which was later renamed to SAS/C.
SAS/C is just an improved version of Lattice C with MegaDebugger + other utils.
I don't care about MUI, RTG, etc. I prefer original A500/A2000 (and A3000) computers ... If I want to keep upgrading an Amiga to be modern I might as well use a PC (which I have several).
You sound exactly like me. This means our brainwaves are oscillating at the same frequency.

I Love my SASC so logically you will too

I have compiled many exes with it for OS 1.2, 1.3, 2.04, 3.0. Works a treat.
It comes with a text editor which works together with the compiler. Isn't that what they call an IDE?
But I am oldskool, I use CED + AmigaDos because I am too lazy to install the Arexx scripts to autolink CED and the compiler together.
