An IDE made by developers for developers.
There's no fancy HMI going in the way, source code/other things ratio is always maximized. There's Git support (among some others I think).
I'm even using it for non Qt project.
The "worst" I've done is:
- make a project with STM CubeMX and generate the code
- using some bash scripts, I extract source files and parameters from generated file to produce a QtCreator project
- enjoy editing with syntax highlighting, completion, even a simple refactor function (ok, semi intelligent rename across multiple files)
