Sorry that nobody has chimed in to give you any ideas, myself included! Sorrier to say that I really don't have any ideas to give you. I can appreciate what you're doing with the font icons, but personally, just for me, I find them a little distracting or "cluttery" when there are a bunch on the ship sheet. I think a lot of these icons would actually be great as counters for other things.
As to leaving for other games, I'm still addicted to Starmada. Just enough complexity of play options to have fun and avoid a trigonometry-level popsicle headache. I like the gameplay of Nova now that I have gotten enough games under my belt, but I must admit, I do miss some of the design flexibility of earlier editions.
If it makes you feel better I'm actually working on a good sized ship project related to my Terran Republic setting. I've been toying with a bit of a steampunk setting (just a whole lotta notes at this point), and I believe you had something in the works from the Iron Stars setting that I am interested in.
Have no fear, there are a few of us around that probably aren't going anywhere, even if we do get awfully quiet out there.
Keep doing stuff and there are at least two or three of us here in the interwebs that will see it and appreciate it even if the rest are gone!
Besides, it's summer, and some of them could be playing outside. They'll be back when the weather turns!
Cheers,
