<Leader> bind error in plugins

[Tiny-Box]

According to the document, if I want to modify the value of <leader>, it‘s recommended to modify .vimrc.local, but it doesn't work about ex-gsearch.

Because the loading order of the .vimrc files, .vimrc.plugins will be first loaded.
On line 48~52

Plugin 'exvim/ex-gsearch'

call exgsearch#register_hotkey( 100, 0, '<leader>gs', ":EXGSearchToggle<CR>", 'Toggle global search window.' )
call exgsearch#register_hotkey( 101, 0, '<leader>gg', ":EXGSearchCWord<CR>", 'Search current word.' )
call exgsearch#register_hotkey( 102, 0, '<leader><S-f>', ":GS ", 'Shortcut for :GS' )

is default '' at this time. Even if I set the value of <leader> in .vimrc.local, '<leader>gs' is still \gs.

There is a dirty fix way: set the value of <leader> on top of .vimrc.plugins file, but it destroyed the previous design about load order. It's better way to modify register_hotkey function.

Will the mapleader variable solve your problem? Basically, it will re-map the <leader> to any key you wish. You can learn it from :hep mapleader in Vim.

Did I use the wrong way to set the value of <leader>?
I insert one line in .vimrc.local:

let mapleader = ","

In vim,
:echo mapleader is ,, but if I want to global search current word under cursor by <leader>gg, ,gg doesn't work, \gg can work well.

My system is OS X EI Capitan 10.11.5, the version of vim is 7.3.
