We've had a lot of requests for Vue. It's not going to be a walk in the park, and we want to make sure we support React well before we add more surface area. But we're not super tightly coupled to React, so (hello, Dunning-Kruger) it shouldn't be impossible! If you're technically minded & want to have a chat about helping us explore that, would love to chat more!
Fair enough. Your decision to focus on one platform first, while still maintaining a relatively generic / flexible codebase, is definitely the optimal one. My interest in Vue stems from me selecting it as a front-end framework (FEF) of choice for my startup (work in progress). I have selected Vue after doing some relevant, but limited, FEF research; however, I might change my mind and go the React way at some point in the future. I'm certainly technically minded, but not an expert in JavaScript and Vue/React. So, while I love helping others, where possible, I'm most likely not the best person to help you explore the potential Vue support for your product. I might be a future user, though. Good luck!
