They should add the option to sneak out of the top of the temple if you didn’t enter that way.
You can go further into the temple into the beginning of the underdark and use the teleportation circle to fast travel. I know you could also just fast travel from the map, but it feels less like cheap exploit this way.
I would also like a feature where the game autopauses when a trap is detected like in BG1 and 2.
That said, I haven’t really had a big problem needing to reload much.
