A bottleneck to Character Sheet development is having Pro Subscription to Roll20. There may be many developers willing to help create character sheets, but don't have the funds/desire/need for a Pro Subscription. Open Custom Character Sheets to everyone, so people can develop/test Character Sheets for the Roll20 Community. To help keep the value of the Pro Subscription available, any non-Pro games using the Custom Character Sheet could be limited to only 2 people (1 person if you're really concerned about it). This would allow people access to the necessary screens to code and test their character sheets prior to uploading to GitHub for the community.
