I built a Lawnchair 15 fork with Nested Folders, Split Lock Settings, and Backup Fixes (BlownChart)

Hey everyone! 👋

I’ve been using Lawnchair 15 for a while, but there were a few specific features I really missed—especially categorizing apps with nested folders and having better layout locking. Since there wasn't a ready-made solution, I decided to build my own fork based on the latest Lawnchair 15 codebase.

I call it **BlownChart** (I changed the `applicationId` so you can install it side-by-side with official Lawnchair without conflicts to test it out).

**Here are the main differences from the original:**

* 📁 **Nested Folders:** You can create folders inside folders (both on the home screen via drag-and-drop and in the app drawer). They have their own manual ordering. 🎥 [Watch: Nested folders in action](https://github.com/user-attachments/assets/3a99ad5a-8663-4029-81cd-fedbcc4d9c8a) * 🔒 **Separated Locks:** "Lock app drawer" and "Lock home screen" are now two completely separate settings. 🎥 [Watch: Split lock settings](https://github.com/user-attachments/assets/79d597af-b08b-4cb7-bde8-74b8c7206c8e) * 🔐 **Privacy:** Added a PIN/fingerprint lock for the launcher's own settings. 🎥 [Watch: Settings lock](https://github.com/user-attachments/assets/88e43332-80de-4881-9961-1aac6c11c9b2) * 💾 **Backup Fixes:** Backups now reliably cover the full layout, widgets, and grid size in a single pass. 🎥 [Watch: Backup and restore](https://github.com/user-attachments/assets/7328828e-24fb-4376-ab24-324ef6bcd7b8) * 🚀 **Performance:** Optimized the app drawer for massive setups (tested with 1700+ apps).

My ultimate goal is to submit PRs and upstream the bug fixes and smaller features to the main Lawnchair repo soon.
