Fantastic puzzle. It took me quite a long time to get to the initial realisation that lets you break into the puzzle, lots of fun after that with a nice blend of connectivity and typical Fillomino logic.
Thank you very much, I’m especially happy to get feedback on bonus puzzles.

Just wanted to chime in and say that I also enjoyed this puzzle’s solve very much. I sat and stared at a mostly empty grid until I remembered the technique you mentioned in rot13, which led to plenty more interesting steps to discover. Thanks!
