Sorry, I absolutely do not intend to support Internet Explorer at all.

If I did try to support IE, I would have to start by removing a bunch of features. And then 60% of my development time would be spent trying to make things work in IE. IE was obsolete before it was retired. Now even Microsoft says it isn't a valid option for web browsing.

Incidentally, this topic has been covered before (and I offer a bit of a workaround in this discussion).

Safari is a different story. I am overdue to have a sit-down with Safari and try to coax it into playing nicely with osTicket Awesome. Chrome, Firefox, Opera and Edge are all very good at rendering web pages according to web standards. From a web design perspective, Safari is the new IE. 🙁
