Pin the "digitally sign" button or "certificates" toolbar to the tools menu on the right hand side
Could you please allow users to pin one or both of the above options to the tool menu, or the top ribbon, to allow one-touch use of this feature. It's such a commonly used feature to be buried under 2+ clicks.

Thanks for the feedback. we have logged a bug for this feature request.
Meanwhile, you can drag the certificate tool to the RHS tool panel and use that.
