display diagnostic count for all open buffers and all buffers with diagnostics in the picker

[bindsdev]

Buffers, next to the file name, should show the number of errors and/or warning present in the current file. The number could be colored red. If there are more than 9 errors and/or warnings, "9+" could just be displayed, similar to on VSCode.

Is this about the bufferline or the buffer picker?

Bufferline. Although it could be another idea to have files with errors or warnings be colored red in the buffer picker.

I just realized that the buffer picker existed recently. A similar idea could still be implemented for the buffer picker. Buffers with errors and/or warnings in them can be highlighted red (as per my previous suggestion) in addition with the number of errors/warnings being displayed next to the path to the file. In the picker, since there is significantly more space, we could display the true number of warnings/errors without having to do a "9+".
