I thought up a new game aid and posted an article on what it is and how to make them a little earlier. Head on over to Aerospace Movement Markers to see how to make them.
I also wanted to say that the Mac version of Roster Builder is moving along, slowly. I am putting a couple new features and bug fixes in, which will also appear in the next version for the Windows side of things as well. I use the same code for both platforms with an "which version is this again?" IF statement when there's differences.
Once this is out of the way (and I get my Ender 3 working properly) I'll start working on the next version of See Mark Paint..
