[Feature] Tooltip support

I'm not really sure what is involved in that feature. When using diagnostics via e.g. ALE, I get tooltips in gvim such as:

neovim-gtk currently doesn't seem to do that:

I think this feature is disabled in neovim, but not sure. Just don't know where to get this tooltip info.

Afaik it's called balloons and it's removed in neovim indeed. https://github.com/neovim/neovim/issues/2544

Then I wonder how this was implemented in gonvim:

@hasufell they probably just reimplemented it on top of nvim somehow.

hm, yes it implemented using nvim api, https://github.com/dzhou121/gonvim/blob/c264bb83afbfe10c2d4991037142c169ce6519c3/editor/locpopup.go#L135

Interesting, think it is possible to implement same way

Right, that would be a shortcut, that will be useful short-term at least.

However, gvim seems to have a much more powerful approach there that even integrates with https://github.com/autozimu/LanguageClient-neovim showing type information on mouse-over:

However, errors are the most important thing, probably.

+1 for this feature. Tooltips are really helpful and it will be great if this is implemented.
