+- W600 and/or W800
+- LN8825
+- host-native family
+
+### Tools
+
+- move all UF2 assembling/uploading/processing tools (as well as `uf2ota` C library) to a separate repository, possibly rewriting parts of it again. Make these tools CLI-usable
+- write OpenOCD flashers, using uf2ota library + FAL for partitions (same repo as above)
+
+### Serial
+
+- allow selecting default output port for LT logger, as well as for `Serial` class (without a number)
+- choose output port during runtime, too
+- enable/disable auto-silencing of SDK output, as well as an option to disable it entirely (compile-time? run-time?)
+- configuration of RX/TX pins
+- SoftwareSerial library
+
+### Other
+
+- watchdog API
+- `Preferences` library
+- test/fix IPv6 on different families
+- what is `PowerManagement` at all? probably useless -> remove
+
+## BK7231
+
+- WiFi events
+- implement OTA
+- test & add support for BK7231N
+- add generic board definition
+- fix SSL (mbedTLS)
+- I2C (Wire)
+- SPI
+- BLE
+
+## RTL8710B
+
+- add generic board definition
+- rewrite most of Wiring (it was copied from `ambd_arduino`, and is ugly)
