Can I create multiple repl tabs that connnect to the project repl?
You want multiple tabs on the same REPL? Yes, you can do that in a couple of ways. They'll all involve using a Remote REPL configuration to connect. You can either a) start a REPL using a normal config and then connect to it from another tab with a Remote config, or b) start the REPL somewhere (e.g. in the terminal) and then open as many tabs as you like connecting to that one with Remote configs.
