the whole point of agile is to be short term
Not really. The whole point of Agile is to iterate. This means short development cycles which include review and design rounds to adapt to changes that can and will surface throughout the project. The whole point of Agile is to eliminate problems caused by business, project, and technical goals not changing because planning is rigid and can't accommodate any changes because the process does not have room for those.
This is why this whole "things need to be planned" crowd are simply talking out of ignorance. Agile requires global planning, but on top of this supports design reviews along the way to be able to face changing needs. This requires planning in short-medium-long terms.
Don't blame Agile for your inability to plan. No one forces you not to plan ahead.
Your comment feels half-baked at best. You start to talk about "best editors" but you proceed to present your two best examples and neither has anything remotely related to editors.
CLion is undoubtedly the absolute best IDE for C++ projects, and it's multiplatform on top of it. It's not even a competition, specially if you're using CMake. Using Git integration as your best and single example to refute this is extremely puzzling by how silly it is.
