Hey /,
I have submitted a bug report for the toolbar button issues, for tracking it is:
Case # 00004490: 4.20p1 Niagra System & Emitter Small Toolbar Button Missing
I also created a forum thread for a few other issues/questions with Niagra, hopefully I can get a staff member to let me know whether the issues I listed are bugs or if I’m just using it wrong (since there is no documentation yet):
@ feel free to post issues there too if you want, maybe we can get some answers
