Thanks for the compliment - and cool nickname, by the way. Big ERB fan here.

As for the sector names, I have been pondering the problem. I am coming to the conclusion that adding so many star system AND sector names simply is going to be a mess. In theory, every square ought to have a sector name in it. There's no way I can do that and have overlaps.

Instead, I think what I should probably do is add "region" labels. I can get away with far fewer of those, which will make for a cleaner map.

And since this is all organized in layers in inscape, I can create an alternative map which has just a few key systems - and a lot of sector names.
