Wasn't a fan of 18.1 and when I'd switch between different tabs (windows), the windows wouldn't refresh. In otherwords, If I'm looking at stored procedure A on tab 1 and stored procedure B is open on tab 2, if i switch to tab 2, I still see code for stored procedure A. I just downgraded to SSMS 2016 (16.1) and don't have this issue. I also think SSMS 2016 is more visually pleasing then the newer version. I think sometimes in the unending pursuit to improve software, we end up actually making things worse......
