Lacking interfaces?

[vid]

I started playing with IdaPython recently, and I made a nice progress
in the short time, but there are several things I find lacking. Maybe
I just missed them in reference, maybe they aren't implemented:

1. How to get full description of instruction operands? I was able to
get them with idaapi.get_instruction_operand() (thanks to code found
in GetOperandValue implementation in idc.py). However this interface
seems to be undocumented internal thing. How to do this properly?

2. When structure has enum member (for example FF_DATA|FF_DWRD|
FF_0ENUM), how to get name/id of associated enum? GetMemberStrId()
returns -1, and there is no GetMemberEnumId(). I wasn't able to find
any workaround for this one.
