Hello! I am new to this forum and developing a megaman-inspired sidescrolling game. I have decided to use a tile-based approach in my level design, and am using this really incredible software to help me do so. Screen scrolls are also present in this game, and knowing exactly where a screen starts and ends would prove incredibly more convenient than having to count individual grid squares.
I would suggest having the ability to put up a secondary grid (of configurable size) to divide the map into larger chunks (screens).
Thank you for taking the time to read this suggestion!
