I have been a long time looking for IDE with vim capabilities. Builder just improved its vi mode. Kate and Geany have one. The problem is that they are limited and beyond basic navigation/editing, the whole process of using the full potential of the IDE in vi mode is under documented and you are never really on how to use them effectively. And Onivim2 is not developped anymore. Even finding a simple text editor with a vi mode + mouse copy paste is painful. Gvim is sometimes weird and it is not clear how it handles copy pasting, the new gnome's Text Editor has a vim mode but it's kinda hidden IIRC. Oh and in Kate, I can't insert "g" in vim mode. I have to take time to report that bug some day.
