Showing Coordinates

I would like to request a feature where you can display coordinates while playing in Minecraft Java Edition. This feature will be very useful. As Java is supposed to be better than Bedrock, and Bedrock has that compatibility, having that on Java would make it much better for users as well.

Also, being able to join people like on Bedrock. You can only join people on same LAN connection. Being able to join like on Bedrock would also be very useful. Minecraft Java User Experience has been the same for quiet a while now, an update would be much appreciated. :)

Thanks!
