First, I want to thank the LVGL and Squareline Studio teams. I have created some works using LVGL and SLS. As a ui designer I focused on developing clean and neat user interfaces. I utilized the SLS OBP features and i created OBP for the devices I have, to making the process smooth and hassle free. You can check github for the code and youtube for a walkthrough of how I made it.
Using images typically consumes more memory and processing power. Building ui with built in widgets and manually designed panels might be more efficient.
