Any solutions to Powering Up / Down yet?

Hello HIVE,

I've been silent for the past day or so, only commenting here and there. I was hoping I could power up my HIVE tokens by now, have access to my wallet etc. as I need to start powering down an old account and transfer the stake over on this one.

I know we have the PeakD interface or the Keychain extension, but none seem to have a working Power Up / Down function yet. Any ideas if there are other alternatives, other ways to Power Up / Down?

I'd really appreciate the help if anyone has figured it out. I will also write a quick guide for everyone if there's such a solution out there as I'm sure plenty other people are looking for the same thing!

Thank you!
