Wow, I didn't know you could use Spotlight to do calculations! Thank you!

For anyone on macOS who doesn't know, hit command + spacebar.

I feel like I spend all my time waiting for Intellij IDEA to start up and reindex everything... Does anyone feel like it is snappy?

neither of those two actions are "snappy" but I guess its understandably so.

reindex everything should be happening that often unless caches are cleared; you might want to raise an issue if it's happening more often than you'd expected

what I'm more bothered by is the regressions that creep in either IDE or official plugin updates; I've spent some amount of time on every update I'd deem wasted, just to find a YouTrack issue on it :\

Feel the same. It is always doing something, especially with a big project.

Try to change default GC to G1.
