Reading through,
It seems to me that there are common application implimentation questions,
The lvgl documentation is great in describing how all the individual components work. However it can be daunting when one is faced with structuring an application and general usage philosophy and conventions adopted for particular applications, especially complex ones.
Can I suggest an “Application” (or similar) catagory where these matters are discussed and templates shared.
Users could contribute templates etc, this could be of help to anyone with “How to ago ABOUT” as apposed to “How to” questions. In other words, a means of making it easier to make important design decisions.
