I'm a relatively happy user of Vim emulators in IDEs (mostly in VS / IntelliJ / Eclipse); e.g. I might do a cw / ciw / ct[first letter of next word in variable name] and then hit the IDE's shortcut for rename refactoring. Simple macros for tedious repetitive tasks. For this, I find emulators sufficient, a kind of "best of both worlds". I suspect my usage of Vim itself is fairly basic, making this workable. What issues did you find with this approach?
