Now, coc looks more modern to me.
Have you forgotten the signature.floatConfig?
I add border and change the highlight for diagnostic and hover. BTW, as a tmux user, I want an focusable option :)

edited: has supported signature.floatConfig and focusable

look weird if I change the borderhighlight.

Found an issue for scrollbar in neovim:

[chemzqm]

What's wrong with it?

[kevinhwang91]

The lower part of the scrollbar is , should it be padded with |?

[chemzqm]

No, neovim doesn't show float window content with lower index when using winblend, and I don't want to add text to scrollbar buffer

[kevinhwang91]

How about composing the scrollbar and the border as a single window?

[chemzqm]

Not worth it.

When there's border in docs float, it gives the impression that the docs float is smaller/bellow than the pum menu (which can't have a border at all sadly) because the top border of the doc float occupies line height, with actual border line lying at the middle, hence it's unaligned with pum whose background covers all the line contents as a whole, giving the impression of an outer edge.

I don't have much idea whether that could be made better.

edit Works on neovim 0.4.4 so using that for now, will open an issue when I look into it further.

My floating windows used to work, now no longer. Using coc.nvim + nvim 0.5.1 + clangd

When I run :h coc-config-float I get
E149: Sorry, no help for coc-config-float

Could you explain what this means? And also it would be great: what should I do about it?

Same behaviour with nvim 0.5.0 (stable) and 0.5.1.

Interestingly sometimes I do see the floating window as it flickers up then shuts.

Sorry if this isn't the appropriate place to post this, I'll submit an issue if necessary instead.

@Arghnews I run 0.5.1 and have no issues, either with functionality as with the help entry.
