What is the correct behavior of "previous window" (C-\)?

[ywpkwon]

Thanks for this great plugin!!

Let's say 3 windows (2 tmux panes {shell, vim}, and vim split).

|-----------------|
|    shell        |
|-----------------|
|  vim buffer1    |
| - - - - - - - - |
|  vim buffer2    |
|-----------------|

C-{hjkl} works well for me, but I'm wondering about C-\.

Let's say I'm working on buffer1, and then buffer2.
C-\ will go back to buffer1.
C-\ will go again to buffer2.

At this moment,
[case1] Hitting C-\ will go back to buffer1

[case2] Instead, with the mouse (or tmux <leader>q1), I jump to shell.
I want to work again, so C-\ will go back to buffer2.
Up to here, it worked as expected.

So, now at buffer2, what should happen when hitting C-\ here?
Shouldn't it go back to the shell?

But in my case, it goes to buffer1 as if it's the [case1] (the previous split inside vim). Is this intended or my setting is wrong?

Thanks for the kind words, @ywpkwon! Hmm, I'll be honest that this functionality is some of the subtler stuff and I'm frankly less familiar with it. I wonder if the usage of the mouse is causing the disconnect?

But what if the jump comes from tmux <leader>q1? (<leader>q displays numbers for each pane and let you jump.)

My point is that, once focus comes from outside vim to one of vim splits, I feel like "c-\" only switches between vim splits instead of going back to outside vim.
