IJ has always been an amazing IDE, and I have been a loyal customer for years. However, over the last few releases, I've found IntelliJ to have gotten slower and slower, and buggier and buggier.
I run IJ on a 32 core Threadripper machine with 64 Gb of memory, and find it to hang in the editor way too often. For example, I just made a few changes that kept hanging my IDE for a few seconds at a time. Then, I tried to undo the changes, and each undo caused another hang, each of a few seconds. Yes, I've filed performance issues in YouTrack in the past (here is one: https://youtrack.jetbrains.com/issue/KT-27106, open for 6 months), but few things ever seem to get fixed. I can only imagine the issues people with slower machines are having.
On top of this, there are issues like this one I created two months ago: https://youtrack.jetbrains.com/issue/KT-29352. Because of this, my colleagues who use Windows can't even execute applications from within IJ -- this is not a minor issue! No action taken by JetBrains as far as I can tell.
I know you're trying to gain users with new features. But a slow and buggy IDE is more likely to turn users off of your product, features or no features. I'd really recommend taking a hard look at what your product team is focusing on.
