Though the Public BETA for Bonsai is coming (BETA 4 is just out and BETA 5 will be public), the GroupWiseR experts offer you a Preflight Check for Bonsai.
You can challenge their team of GroupWise experts by submitting your (longstanding) requests for improvement using the form on this page.
The GroupWiseR team will investigate all issues and will get back with you, hopefully with the answer “Yes, this is solved”! (If not, file for an enhancement ;-) - Gert/GWCheck)
