+### Known issues
+
+- `format/0` overlap with jq builtin `format/1`. What to rename it to? `decode_format`?
+- repl expression returning a value that produced lots of output can't be interrupted. This is becaus ctrl-C currently only interrupts the evaluation of the expression, outputted value is printed (`display`) by parent.
+- Auto complete of non-global variables is broken. `scope` is broken for variables.
+- `tovalue({bitsformat: "base64"})` only affect root value.
+- Unknown field filling is currently only done on root, should be done per "framed" decode.
+- Sub buffers range is broken, could have a different size in parent (ex: compressed).
+- Symbolic values should be more intuitive, should not need to use ._symbol.
