Neovim: E518: Unknown option: balloonexpr=colortemplate#syn#balloonexpr()

I'm getting the following error on loading the filetype plugin. I tried both on Neovim stable 0.4.4 and nightly 0.5.0.

Quick look at :help 'balloonexpr' shows that it's removed?

Thanks for reporting. I'll push a fix during the weekend. The error is harmless.

i noticed when doing :call colortemplate#syn#toggle() i get a number of errors that seem to be caused by using vim features that are not available in neovim, such as the object literal syntax #{ ... } and the text properties API call prop_type_add().

Set g:colortemplate_higroup_balloon to 0.

I will add a check to prevent those errors.

You shouldn't get any errors with the current master, regardless of the value of g:colortemplate_higroup_balloon.

works like a charm, thanks for the quick fix!
