Full end-to-end encryption
It would be nice for business users to have end-to-end encryption (not jus tin transit but also storage). Many companies currently won't allow their employees to use wunderlist because it doesn't offer this.
GDPR means this will sink or swim for business. I will have to delete this if I can no longer use this for business.
I use wunderlist both at home and at work. Attachments are not encrypted when stored, which means folks at work can read my personal attachments and people with access to my personal PC can read work attachments.
I am more concerned with attachments than with lists, but only the person that is signed-on to Wunderlist should be able to read attachments.
I see that this is not a very popular feature request and that's really a shame. When we trust third parties with our information and pay them for their services they should be expected to do reasonable things within thier power to ensure the security of this data. End-to-end encryption should be the de facto standard in Wunderlist or, at the very least, an available feature for those who would like to have it. I'm sure that Winderlist has the customers privacy as a top priority but even given that there are times when things happen that are out of ones control. Good intentions account for little when things go sideways and not taking all available measures to keep those that support you safe is negligent and short sighted.
It would also be helpful if at least notes of a task can be encrypted
