To put it in a friendly way IntelliJ is very useful/handy/productive for Kotlin K development simple smile however just like the other Java ☕ based IDE's (eg NetBeans, Eclipse) it can be a resource hog piggy at times (uses a lot of CPU and memory), and overkill for some situations (too complex?) ⚡. In one instance when some simple edits 📝 are being made to a small # of Kotlin K source files it makes much more sense to go with a light weight 🔦 programmer's text editor (eg Atom, VS Code). Some of the programmer's text editors are not that much better with resource usage, especially when they are written in JS piggy (eg Atom, VS Code) but are enough to make a real difference.
