Hello Support or Community Manager,
I have installed latest sugarcrm 7.7 and get to know that you guys have not enable "Create" or "Select" button on the "Campaign Log" subpanel under any module that subpanel display, which is very good.
My suggestion is that as per flow we can't use that buttons then why we not remove the buttons from UI rather than just not enable that.
I have attached the screenshot that would make you more clear what I am suggesting you for next release. If you can't do that then please give please let us know why you can't do that.
If you have any questions then please let me know.
