Hi, I'm not really sure to understand the "self-contained application" concept. Does it means that if we want to build Beacon sheets, these won't be included as is in the VTT but in a different tab on our browser? If so, how sheets will be displayed on the VTT, especially for the GM? Sheets will be open in a new tab, like when we detach sheets currently? I suppose then that every rolls will be synchronized with the VTT? I do like the rolls history by the way, just for the player, pretty cool! To be fair, I think having the option to build kind of sheet applications is pretty cool, even if it requires developer skills, it allow more creativity for people who have time and desire to involve. As long as older sheets are still available in long term. I don't think people will recreate, at least at the beginning, as many as sheets with the Beacon SDK, so if the plan is, at some point, to remove the current system, you might lose a lot of "games support". I don't know what's your ultimate plan, but making a Beacon sheet creator to help people create Vue/React (or whatever) awesome sheets seems quite ambitious. The best start would probably be as mentioned a documentation with basic examples, exactly like it exists currently. For sure, develop with a javascript framework will be something interesting for actual devs or for those who want to learn a framework because they are attracted with the job. You will probably lose people that only makes custom sheets (not published) and don't really have a knowledge and skills in development. I have a friend of mine that I helped to make a custom sheet for a custom rpg, and I can tell that he probably won't commit in a Beacon sheet creation. He does not have big problems to make HTML/CSS content (although he doesn't have that much good practises), but he struggles a little bit on sheet workers. He manages to achieve his goals with examples and help, but learning a javascript framework is on another level. In the end, I really suggest to "never" get rid off the current way of making character sheets until you are able to really give a user friendly app to create a complete sheet. I mean, like having a complete app with options which create the code in background. I think this is pretty huge, I'm not really sure that is the thing I would love to see released prior to other improvements/features at the moment. However, I'm really excited to test the SDK and will probably sign for the closed beta, even if the game I cover is not that much famous :D By the way, thank you for all the work done there and thank you, the community, because I think the community contribute a lot to make roll20 a very good VTT for everyone!
