Option to open :LspDefinition in a split

[ghost]

Hello,

Love your plugin especially the fact that it is written in vim script. However, one of the feature I'd like to use is jumping to a definition in a split. Language client provides this feature:
https://github.com/autozimu/LanguageClient-neovim/wiki/Goto-definition-in-a-split

Note that this is not the same as doing: :sp<CR> :LspDefinition<CR>
The above way would open up a split even if lsp was unable to find the definition which is not what I want. I only want to split if the definition exists.

This should be easy to do. Its the only feature I miss moving over from LanguageClient. I'd really appreciate it if you can put this option in (pretty please).

Also: jump to a definition in a tab would be great.

Here's a workaround - put this in .vimrc

nmap \gd :LspDefinition<cr>
nmap \gt :tab split<cr>:LspDefinition<cr>
nmap \gs :sp<cr>:LspDefinition<cr>
nmap \gv :vsp<cr>:LspDefinition<cr>

This is now possible with <mod> which is the vim way. #776

Examples:
usage:

:leftabove LspDefinition Splits horizontally and opens a window to the above.
:rightbelow vertical LspDefinition Splits vertically and opens a window to the right.
:tab LspDefinition Opens a window to the new tabpage.
