Several questions

Several questions

I have imported my notes from Evernote since I am trying to find a new "home. However I have several questions:

1. The OCR in images doesn't work, only works on PDFs. Is this normal? I am trying the premium account. 

2. Is it planned to have a calendar integration with outlook? 

3. Is it planned to have tasks? 

4. Does Nimbus have backlinks?
