Documentation on cloud could be improved. For example, they could introduce video tutorials for implementation. 

In the next release, they could perhaps enhance the locking as an additional feature. For now, it's limited to 90 days. Maybe it should be enhanced to be GDPR-compliant.

It has been really great. We don't have any complaints about it at all. We've only had one or two very minor glitches, and they were just in passing.
