I use the following to auto-close coc-explorer if it's the last open window:

autocmd BufEnter * if (winnr("$") == 1 && &filetype == 'coc-explorer') | q | endif

which is a suggestion I found based on NERDTree's suggestion for auto-closing their file browser:

autocmd bufenter * if (winnr("$") == 1 && exists("b:NERDTree") && b:NERDTree.isTabTree()) | q | endif

Beacon prevents this from happening with default settings. Any way around this?

E: I'm not sure if setting beacon to ignore buffers would work but I don't really understand how to implement g:beacon_ignore_buffers = [\w*git*\w]. An example with multiple ignores would be very helpful! Thanks!
