Very good analysis of a function or procedure, but not enough of a couple of goodies.
No block size for instructions.
Why is there no code coverage for "case:"?
//jmp ptr [index * sizeof(duint) + switchTable] - I have never met
ok. Why not mov reg, dword ptr [index * sizeof(duint) + switchTable]?
After all, one of the features of such a constructor is jump_reg. And the pointer to the table is very often very close.

And if not difficult, add to the structure "FunctionInfo", total size of all instructions

The issue with detecting jump tables properly is that it requires heuristics that are very error prone. I think developing these is a bit out of scope for x64dbg, but I will keep this open in case somebody would like to pick it up.
