cw8: Kerbal Engineer basically just displays total ⌂V for all stages or ⌂V for every single stage.
Yeah, I very much scrutinized your screenshot for the mod display. I'll certainly come to use it, it's not unrealistic to assume that kerbal engineers would be providing that info. Also I'm oddly reassured by your troubles, in the sense that this mod will not magically solve everything if I install it.
I'm currently landed on Duna, doing science (I have a dumb habit of sending labs to biomes I explore for the first time : it would be much more clever to simply send a command pod first, and only send labs on subsequent trips, gathering quick experiment data first instead of staying there for ages-long local research). But I'm a bit scared to attempt to return, I have no idea yet if I'll be able to. But as I'm still calibrating my rockets through trial-and-error, I'll have to do it before sending another mission.
[Update : Just enough to lift back to Duna orbit. It's, well, rescue mission time, I guess.]
I've been eyeing the clouds and chatterbox mods (but I wonder if the latter fit with the kerbal look). I also admire those who go full earth-scale mode, I'm not ready to leave smurfland yet. I've also considered seeking a mod to deploy solar panels collectively (like we do for landing struts and lamps), but I just realised that "action groups" should solve that. KSP itself has features I haven't explored yet, so it may be early for mods.
I also haven't found a way to save properly (as opposed to quicksaves) without having to go to the space center and back. Maybe there's a mod for that...
