Feedback from user: """ Ok, this is a well-crafted tool, the UI/UX is awesome, it almost gave me the spark I need to go back to the game after... 5 years away. Congratulations! The software engineer in me salutes the software engineer in you. Now, can we please have mirror mode when placing at least the hull? Also, COPY PASTE, please? Also, I noticed that when placing adjacent hull, it doesn't join them. """ --- Maintainer triage (2026-01-15) Order: 6/16 Impact: Medium Estimate: S/M Tags: priority:P1, hull, rendering Summary: Make adjacent hull tiles visually merge/“join” more like the game (and refine auto-wall perimeter rendering). Notes: Hull tiles are rendered per-tile with borders, which visually separates adjacent tiles. Hull “walls” are auto-generated using 8-neighbor logic, which can place diagonal wall tiles and look like seams/joins are wrong.
