Question: When using ctrlp, I can open a selected file in a new vertical split using ctlr-v

However, the new file open in the left split and the already opened one goes to the right split. I'd like the opposite to happen : opening the new file in the right split.

Workaround : Using ctrl-w + ctrl-r afer opening the file to invert splits

Answer: 
If you create the setting in your vimrc:

```
set splitright

```

it will open every file you open in a vertical split on the right side (not only CtrlP).
I'm a few years late here, but from the plugin :help docs, it says that you can configure the new tab position:

***a** - after.  

**b** - before.  

**c** - the current tab page.  

**l** - the last tab page.  

**f** - the first tab page.*

For your desired behaviour, you should include this in your .vimrc or the configuration file of your editor.

```
let g:ctrlp_tabpage_position = 'ac'

```

I hope that someone in the future find this useful.
