I found Unite.vim as a very very powerful plugin. It has replaced few plugins I have been using before. Installation of the unite.vim does not bring us any mappings and requires some initial configuration.
You may start with adding mappings for most usable features:
Now, if you press
<C-P> you will have a file search window similar to CtrlP plugin search. With
<space>/ asynchronous grep through content in files and with
<space>s a search through buffers. And, actually, it is amazing.
You can go further and add few useful mappings in unite window for navigation and window opening:
Now you can navigate through files in Unite window with
<C-k> and open files in a new tab, horizontal split window or vertical split window with
<C-v> in accordance. Pretty useful.
Also you are able to customize a window position, size, preview settings etc. with profiles:
It is awesome!
Unite.vim is very powerful. It is able to do a lot of stuff for everyday usage. And with a proper configuration it becomes an indispensable plugin.
