Neither Ctrl+T nor Ctrl+O in IdeaVim always return to the previous location when jumping to something in any way.
Yes, after something like Ctrl+], you can jump back to where you came from using Ctrl+O. But there are all kinds of different ways to jump around.
I would like a set of shortcut keys that makes it consistently jump back to where I came from, regardless of how it jumped to something. Be it through a Vim action, or an IDE action, Ctrl+O, and Ctrl+I ought to just let me go back and forth. Right now, it seems like a horrible confusing frustrating mess.
