Those are all great ideas! LightBurn currently doesn’t have a queue system - to do per-run customization of text your best option is the Variable Text feature: Variable Text in LightBurn - LightBurn Software Documentation
Though, that wont work with the designs, as you mentioned in your use case. We do have a HotKey Editor: Hotkeys - LightBurn Software Documentation and you can select individual layers with it. Look under the ‘Cut Palette’ section, that may work well for you
We welcome all ideas for new features over at our Fider.io site here, so we can keep track of what is most desired by our community: Voting System for New Feature Requests - Fider
