No snippet in the middle of a line

HI,
I think this is more a demand for improvement than a real bug.
I noticed how often the Snippet command would yield nothing when in a middle of a line (although a lot of my snippets can be triggered anywhere).
I tried changing line 876 of ../autoload/fzf/vim.vim and adding parameter to change the list of snippets seems to give me a good result. The line I use to get the list of snippets is :
--- snip
let list = UltiSnips#SnippetsInCurrentScope(1)
--- snap
Is it possible to add a parameter for the selection of the snippets (something like param = 1 would give all possible snippets) ?

By the way I really appreciate FZF, using it more and more on CLI with zsh and in vim + neovim ; I'm a great advocate at work of it,
so a big 'Thank You' for making FZF,
Cheers,
Apol
