My regular IDE is IDEA with a bunch of language plugins, so I think I have a reasonable idea where you're coming from.
The idea is to have a tool that can be either a lightweight text editor when you want that or a full on IDE when you want that, and potentially use a remote (could just be another machine on your desk or could've a container on a server) machine for the heavy lifting parts.
I like the premise, but the public beta (or whatever they're calling it) is a little rough to use daily, for me.
seems much slower than the "new UI" in the regular product line. JetBrains makes lots of effort in UI matters, but seems to pay zero attention to UI latency. Odd.
