i'm ...uh... old but that's my list as well. 1. function. can I get there? can I get back? can I fix it something goes wrong? my creations aren't always visually pleasing. but they work. After they work I prettify them. :-)
echoing others I have righted a few landers with eva'ed kerbals. (and failed more often) but another trick I've used is retracting/extending one or more landing legs to get the ship to roll the direction I need.
