I went ahead and bit the Pro bullet on Roll20 last night and built a custom character sheet for FrontierSpace. :D
In this image you can see an Abilities and Skills macro's output in the chat box( makes it handy instead of looking at your character sheet). The "Input Value" box is a Skill-Check macro. It pairs all the abilities with skills that I believe most Referee's would use.
Here you can see that Ighim Moore attempting a INT+Tech skill check to try and locked down all the doors to this area. He didn't count on one Spaceport Police getting here so quick! The police fires an electro stunner and misses with a roll of 97. The macro then "whispers" the rules for STUNNER WEAPONS. Finally Ighim decides to shoot back with his TGC Blaster. A miss! lol.
You can see the macro list the name of the target and if they are wearing a screen.
This is the beta character sheet. In addition Ighim rolled initiative. You can see the die codes I used and showing how it adds to the Turn Tracker.
Here is the Electro Stunner weapon. After you select the target to hit, the macro asked you if the weapon is set to Stun or Damage.
