Hello,
Consider the scenario as OpenEMR is having multiple admin,One of the admin has done some changes in the instance,the person who made changes cannot be known, until the admin checks for the log(Administration>Other>Logs).
So we are having some suggestion to add last login details in the top right corner of the page(Refer the screen-shot). This feature will be available only for admin login.
Please share your feedback.We are ready to come up with code changes.
Thanks,
ViSolve
