Thirty years ago is 1993, and I was a junior dev using CodeCenter on SunOS. It was a nice editor/debugger with a C interpreter mode that iirc let you inspect aa variable's history and un-execute lines of code.
A few years later I was using SparcWorks on Solaris. When I realised you could pause on a breakpoint and hover the cursor over a variable in the editor to see its value, my brain nearly fell on the floor.
A few years after that I moved to PC development using Visual C++, and then Visual Studio 97 on NT4. Drag and drop UI builders for Windows and Web.
And 30+ years later I still spend a significant part of my working day in VS.
