A small gripe for me was startup time of JetBrain IDEs. Another small one is that they need /dev/null redirection because they spew weird errors to stdout/stderr.
A big one: on Windows, do they have a WSL1 or WSL2 integration now, i.e. cam they run/debug the compiled artifact under Linux? Use Linux-based compiler/toolchain?
The expected workflow is to launch it once — say, when you come to work — and have it running for the rest of the day. The startup time is completely neglible if you do that. And well, running GUI apps from a terminal is likely to flood that terminal with logs (which is why I launch them outside of terminals).
