At first it looked neat with the new features, but as soon as I realized they COMPLETELY REMOVED the block function, I uninstalled it.
Appearing offline to someone does NOT mean they are blocked. They can still send you messages and if you want to appear offline to your regular people once in a while, you also want to appear online again to everyone. Now what would the common user do? Right, click "Appear online to everyone" again - literally everyone - even your once blocked people.
Also, having to use real names is a shitty feature too.
This software is a piece of junk to me now. I hope they don't force you to upgrade anytime soon.
If anyone needs help downgrading to the good version without losing their emoticons, let me know and I'll post a guide :P
