Boiling anything requires a wait though. There's no way around that.
Waiting times in exploration are inversely proportional (more or less) to the amount of effort put into enjoying it.
It can be very easy with lots of downtime, or very complex with little downtime, or anything in between. It's all a matter of individual preference.
The wait is fine. It's a wait to get into a CMD center, wait to land, wait to take off, etc. It's the prep work in the interim that fills the time. The amount of interaction vs waiting with most exploration activities is about like jumping a carrier.
Some would think any driving requires the driver's full attention. Others think it's perfectly safe to watch a movie and/or text message while driving. Individual preference once again.
The big difference is the movie watching texters can't hurt anyone in ED
But you can probably attest that it's quite common to read here about explorers using Netflix or Youtube vids to relieve the tedium, then some who say they've fallen asleep while exploring. I've never done that while raiding a base or fighting a pirate.
As far as the OP, I could see it going like this basically:
Ship needs repair. I need to select "space walk to prepare ship".
Do I have enough materials? Yes.
I need to select the suit that I hope I engineered for space walking.
Ok now I need to enter the airlock. Depressurizing... black screen ... sounds.. now I am outside the ship and there are sparkles around areas that need repairs. I have to use my thrusters to move around and press "E" to repair items. Oops I forgot to bring my welder.. back inside... black screen.. sounds.. now I am back in the airlock. I want to get to the cockpit so I can select suit loadouts and pick the right tools. Now back outside, airlock, black screen, sounds... sparkles... repairs made. Back inside. Man I need an AFMU.
