Because it's not clear, in usage nor in support:
- If you use Feedly Mini (the tiny, translucent icon tool in the bottom right corner of every page):
- "Like" will share the item in Google Reader. You can turn this off in Feedly settings, but then I don't know what Liking something does
- "Save for later" stars the item in Google Reader. I don't see where this can be turned off
- If you "hide" an item from the Feedly view and then can't get it back, just restart the session and it should reappear
- If you authenticate with your Google Apps account, you don't need to fill in the Google Apps Domain field
