Better clarification of inheriting base unit for pay to many

[yangwao]

I'm using pay to many, but I noticed when started using new Electrum, it switched base unit to mBTC and it did not work as I assume. I expected base unit in pay to many is every time in BTC.
However, I can't find where is this feature exactly documented well. Only found this http://docs.electrum.org/en/latest/faq.html#can-i-do-bulk-payments-with-electrum


This leaded me than to this error #2642

• It should be documented, that pay to many inherits base unit
• Choose pay to many base unit in preferences

Thanks in advance, you are doing great job.

it's obvious from the screenshot that the unit is mBTC; no extra documentation is needed.
making it non-inherited would be way more confusing.
